How to color clear epoxy resinHow to color clear epoxy resin


Let’s talk a little about coloring your resin. There are a few things you can do and a few things you can’t do when it comes to coloring resin.  Knowing these guidelines will help ensure resin coloring success.  Then, once you get a handle on the rules of how to color clear epoxy resin, you can learn when to break them.

To get the best results when coloring resin, use colorants designed specifically to color the resin you are working with.  There are two reasons for this:

1. By using the same brand of resin and colorants, you can be assured that your resin is going to cure the way you expect.  This means that the resin should not cure any differently (hardness, clarity, etc.) than without the colors added.

2. Colors designed specifically for a brand of resin should also cure with that color.  i.e. the colors shouldn’t fade or turn a different color once added to the resin.

Can you use one brand’s colors with another brand’s resin?

The answer is *yes*, but with a footnote.  The footnote is that whenever I have done that I have never had any curing problems. I have, however, gotten a different color than I was expecting.

If you have ever purchased a resin kit and noticed that the hardener is a little yellow, you may find that the resin part has blue added to it.  When you mix the two parts together, the result will be clear.   I have experienced problems where I used one brand’s green, yellow and/or blue and put it into a different brand’s resin only to get a color I wasn’t expecting despite the resin curing normally.  You can see what I’m talking about in the results of one of my resin experiments.

Now that you know the basic resin coloring rules, let’s try to break them.  It’s one of the neat things I would encourage you to do with resin.

Here are my basic resin coloring guidelines if you want to try non-traditional colorants:

  1. 1. Try and use as little of the color as possible. Add until you get the effect you want, then stop.  Resin hates moisture, so you don’t want to add any more moisture than is absolutely necessary.

2. Make sure the colorant is as dry as possible. I have used eye shadows and spices from my kitchen cabinet that were not clumped and still a loose powder.

3. Understand the resin you are working with before you try to color it. For example, epoxies can be forgiving about colorants. Polyurethanes, not so much. Something you might ordinarily use to color an epoxy might have great results but may not work with a polyurethane. Polyurethanes are incredibly moisture sensitive.

What are some things you can try to use to color resin?

  1. 1. Acrylic paints.  Go with no more than one part paint to ten parts mixed resin.  Use even less if you can.
  2. Note:  When it comes to acrylic paints, you get what you pay for. Some are inexpensive because they have a lot of water in them. It’s why sometimes when you use acrylic paints, your resin cures rubbery, bendy or not at all. If you want to try acrylic paints, try the ones that cost more because the color is more concentrated. You’re going to get more color in the same amount of paint than what you would in a cheaper paint.
  3. Another note:  Good acrylic paint pigments are about as expensive as resin colors. You are not necessarily going to save yourself any money.

2. Alcohol based colors.

Note:  Some alcohol colors will not keep their color in resin. I have used some brands that are not meant to color resin and have had problems with the pink and purple tones staying pink and purple in the resin.  They will disappear.

3. Powders such as micas and eyeshadows.

4. Glitters

5. Kitchen spices

6. Sidewalk chalk

7. Water color paints

What doesn’t work to color resin?

Oil paints.  They make a globby mess with your resin.

Nail polish. It turns your resin an ugly amber.

Latex paint is hit or miss for me.  I have used it sometimes only to find it can make your resin stringy.

My parting advice?  Keep a resin journal.  Write down your formulas and what you did.  It will be a great way for you to recreate (or not!) something later.

    1. I’ve tried to use alcohol ink and even resin specific coloring but when I use colors my resin doesn’t dry

  1. did I miss you talking about what to use to color polyester resins? I went through it pretty fast.

    1. I am making dice, but i am wondering what I can add to give it a wispy effect without mixing? Does anyone have any ideas?

        1. So normally that would work, but since I am making resin dice, with a mold I cannot see through or see what I am doing, it doesn’t come out properly.

        2. I’ve watched several tutorials on making “galaxy crystals” which you get by pouring the resin into a circular mold (as if making marbles). You pour the resin into the mold(s) in layers & no the person doing the tutorial couldn’t see exactly where she was placing the colors. She did say trial & error was a big part of the learning process when using resins so it’s good to have a backup plan for your “mistakes”. What she did to get the “star swirl” was: she used a white shimmering eyeshadow (left over from a Halloween costume’s makeup) that she pummeled into a loose powder & using a tool (that was like a wooden coffee stirrer) she put a small pile of the powder on the tip, dropped it into the resin, then used a toothpick to do the “swirling” much like you’d do to make a marble cake, & she did this one layer at a time, letting it “set” for a few minutes before adding more resin into the mold and repeating the process, tweaking it here and there for different effects.
          I’d recommend doing a YouTube search for: “DIY your own Galaxy Charms using acrylic resin” or something very much like that & be prepared to have “mistakes”. (FYI: after the resin sets you are able to drill into it using a very small & specific drill bit then you can attach hooks to them for hanging, thread wire through it for jewelry, etc) My opinion; after watching several videos, was that even the “experts” are discovering new techniques & just like everything else in life… “you don’t know until you try… (but let’s not forget about our planet’s health by cutting back on waste.) which was fine by me except the cost of the resin did not leaving much wiggle room in my budget for mistakes(!), resolution: I used clear glue to practice making my “globes” & the resulting “swirly marbles” I used to make sun catchers by mixing them with some various colored sea glass I had & after I put them inside a few antique jars I’ve got sitting on different windowsills around my Apt. They catch the sunlight & create some pretty cool rainbows!
          I do hope this helps someone if it’s too late for you, lol but, good luck & have fun! Remember:
          *When it’s not fun anymore it’s a job & who needs another one of those?!? LoL! TTFN

        1. Hi Kelly, that’s a great question! It depends on the color you are using. Many will not require extra catalyst, but if you aren’t sure, check in with the manufacturer of the color you are using to get their specific advice.

    1. I haven’t had an experience where colors for polyester resin also didn’t work in epoxy. I would love to hear more.

  2. Clarify which type of resin Ice Resin is. You always refer to epoxy resin, and polyester resin, and somehow I’m never quite sure which is which. I have used acrylic paint with my Ice Resin and also Alcohol Inks and have not had a problem. I have also used Pearl Ex, and have fortunately also not had a problem. I used to always use nothing but resin transparencies, or opaque’s but they are not cheap and was looking for a less expensive means of coloring. Thanks Much

  3. I have a question, what am I doing wrong I’ve noticed on some of my pours that when my resin dries it leaves valleys,where it just won’t stay completely covering the painting, can you please tell me what I’m doing wrong?

    1. Was it a paint pour and Did you use silicone in it? I have had that happen to me when I did not clean the silicone well enough from the canvas before I poured resin?

  4. Bonjour à vous,
    Que puis je utiliser pour faire des effets de trous dans la peinture résine époxy, et voir la peinture en dessous? Comme si la résine faisait de la dentelle irrégulière? Je ne sais pas si je me fais bien comprendre!!

      1. I am having trouble with “bendy” results. Sometimes it’s hard sometimes bendy. What can cause that ? I am using Amazing Clear Casting resin mixed 1-1. What is good size for a batch and what color % is too much ?

  5. I have done a couple table pours but I’m having a hard time finding what to use for like a crystal clear blue or green etc.For a sea through colored epoxy.

  6. Hi there ive bought some epoxy resin foor a floor and worktop from metallic magic im just wondering can i use any acrylic paint to colour it as a primer
    Many thanks

  7. I’ve used a*tiny* amount of food coloring and it worked great, India ink is what I’ve used most often outside of resin pigments.

  8. Please can you tell me what to do to get skin tone I have a little dolls head that I need to copy Thanks Jacky

  9. I am on the step of needing to mix resin to pour for a doming layer for some laser cut pendants I’m making. Is there no way around having to mix the minimum amount of 1 oz (.5 oz for each part) the tech told me over the phone with this Alumilite Clear Cast Expoxy resin? Because this is unfortunate. I used some older ICE resin with ink for the base layers and used maybe 1/16th of that 1 oz I mix for the base layer for about 9 pendants and had to let the rest cure and throw away. For this upcoming doming layer on the 9 pendants it means that I will also have to have a whole lot of additional new pendant frames ready to go to use 1 oz. I create the pendant frames by cutting them from wood with my laser machine. As mentioned I only 9 of them now cut out with base layers with black coloring already done. They are each about 3 inches in height and two inches wide. I will cut out more to put in base layers for the new ones to use up the resin I will mix. Is there no way to make smaller batches in general with resin? Maybe the base layers can be softer if one uses less than the minimum? The problem with that is that my pendants don’t have backings. I was planning on adding either a layer to the backs or maybe spray with the clear gloss sealer. Thanks in advance 🙂 ~Brian

    1. Hi Brian, the minimum mixing amount is important because the mixture has to be able to generate enough heat for the resin to cure. This requires a minimum amount of resin and hardener to be mixed together, which varies amongst resins.

    2. I have had success with as little as 5ml (~0.169oz) of [72-hour] epoxy. With volumes that small the margin of error for measuring etc. is much less forgiving though, so measure as precisely as possible, and diligently scrape as much of the remnant component liquids from their measuring cups as you reasonably can so as to not lose component volume and thereby problematically deviate from the required proportions.

      1. I use a syringe to measure out small quantities, 2 ml of resin and hardner each. My resin has always cured hard. The resin syringe can be re-used but the hardner one has to be cleaned or just replaced every time.

        1. Marcellé, your use of syringes for measuring small quantities is such a good idea that I am almost annoyed at myself for not having thought of it.

    3. Not to promote another brand on here, but if you work with resin long enough, you will know that there are different brands for different uses.

  10. Hi Katherine, Thank you for taking the time to reply. I figured that was going to be the answer. Okay thank you. I will just need to have a lot of pendant frames available with each pour so I won’t waste it.

  11. We have a very warm climate (in South Africa) specific things that I need to keep in mind? Thank you for very helpful advice!

  12. hi what resin can be used on chopping boards ive got 4 different types and dont know which one will be food safe, also is there a resin that will rest cutting thanks

  13. I am trying to make a clear yellow or orange. It is clear in smaller pieces but thicker pieces are opaque. How do I get the look I want?

        1. Hi BJ, if you aren’t happy with the hardness of your resin, it sounds like you may want to try a different brand. Which one are you using?

  14. when using micas in my resin once fully cured they tend to be over taken by one colour not necessarily the darkest , it tends to sort of flood into the middle by the time it’s cured. I’d like to try and achieve the agate look but can’t keep the colours Sections more defined
    Thanks for any advice

  15. What about acrylic inks?
    I’m getting ready to try this now wondering if anyone else has used these?

    1. Hi Max, unfortunately, food coloring doesn’t work well because it contains a lot of water. That water can inhibit curing.

  16. Hi, in one batch resin mix i have pendants that dry nice and pendants that stuggle to dry .. please tell me with what are you cleaning a spillige or the sticky on your hands?

    1. Hi Engela, you can use baby wipes or soap and water to clean the resin from your hand. If the resin won’t come off, use a pumice soap.

  17. Can you move the add a comment section to before all the comments, just a little feedback. If it’s an option for course. . Loooove how you speak through your writing, some people have a hard time doing that. I was able to understand clearly enough to read all the way through, that’s rare. Second time using epoxy, first time using color 🤞🏼 here goes everything!

    1. Hi Melissa, if you are using colors designed for resin, those details should be included with the colors’ instructions. Otherwise, if you are unsure, add it into the resin once it’s thoroughly mixed with hardener.

  18. Hi, I was wondering whether I could use satin acrylic paint in my resin. It might be too different from normal acrylic paint, I don’t know. Any help would be greatly appreciated, thanks!

    1. I don’t know Marcia, I haven’t tried that. If you do try, will you let us know how it works?

  19. I am covering old green laminate countertop, I want it to be white with a gray marble streak. Do I need to paint the green Laminate white, or can I make a solid white epoxy? I’m hoping to make a white solid epoxy. To make a solid white what should I add to my Epoxy?

  20. What happens if you mix mica powder with alcohol ink? What is different from using only mica powder without alcohol ink? I saw a couple people add alcohol ink to mica powder but I don’t know what the difference is.

  21. I’m a beginner but am a bench jeweler in real life. After seeing all the comments on too much liquid I’ve had luck with taking food color etc and pouring into a container where I have a thin layer. I let it dry out. Voila! It still colors because it turns into a liquid again but now the liquid part is not H2O but the resin. Seriously doubt it will work on things like latex paint. Am on my way to the hardware store to try and convince paint guy to sell me some sample amounts of tint. Going to put them into little tiny sample containers. Will mix with H2O and let dry out and see what happens

  22. I have some dry watercolor paint that I was thinking of using to color some clear cast resin. Instead of water, I was planning to use some q-tips and Isopropyl alcohol. Has anyone tried this? How did it work out? I’m hoping to get a dark and very faintly translucent effect like obsidian.
