Thermochromic Pigments change color when exposed to different temperatures. Every pigment has a different activation temperature (the point when it changes color). When temperature rises over certain degree, the pigment turns from one color to another or color to colorless (translucent white). But the process is reversible- when it gets HOT or COLD, the pigment turns back to its original color. You can mix Pigments with clear or white glue, varnish, resin, silicone, nail polish, liquid soap, hair dye/mousse/gel, paints, or any medium corresponding to the surface you want to apply on. Ratio of Powder to Binder is 5% to 15% by weight depending on application and how bright you want your colors. 10 grams container has 7 teaspoons. Our Multicolor Packs have 3 different color choice containers - 5 grams each (3 and 1/2 teaspoons each container) Perfect for DIY Color Changing Face Masks, Secret Messages, Nail Art, Epoxy Tumblers, Science Experiments, Slime, Color Changing T-Shirts & Shoes Before ordering, please consider your room temperature, season and decide which activation temperature will work for your specific project. For making Color Changing Face Masks by breathing, choose BLACK to COLORLESS changing at 82⁰F (28⁰C) For making Epoxy Tumblers, Slime or Paint changing color by hand touch, choose activation temperature close to your ambient temperature from 72⁰F (22⁰C) to 82⁰F (28⁰C) BLUE to VIOLET changing at 72⁰F/22⁰C RED to YELLOW changing at 77⁰F/25⁰C GREEN to YELLOW changing at 77⁰F/25⁰C BLACK to PINK changing at 77⁰F/25⁰C BLACK to COLORLESS changing at 77⁰F/25⁰C BLACK to YELLOW changing at 82⁰F/28⁰C BLACK to COLORLESS changing at 82⁰F/28⁰C BLUE to VIOLET changing at 82⁰F/28⁰C For Cosmetics and Color Changing T-Shirts choose 82⁰F (28⁰C) and 88⁰F (31⁰C) Perfect for Creating Original Color Changing Art The most important factor in the color changing process is YOUR OWN AMBIENT TEMPERATURE at time of use.

Consider your room temperature before choosing activation temperature for your project Review: Super reactive, deep color pigments - I've bought the Yellow-Red @59, Red-Yellow @77, Black-Clear @77, Black-Pink @88, Red-Clear @88 and tried almost all of them. My first attempt was to put Red-Clear @88 and Black-Clear @77 in some big box epoxy and inject it into a ring mold... that worked great and the color is super red. Two things I immediately discovered: 1) You can't expect a powder pigment to turn crystal clear. It turns translucent/opaque white. I don't know why I expected a powder to disappear 😅. 2) Finger 'body' temperature is WAY below 88F in the winter... so only the Black-Clear 'kicks' and only a little... In the summer I'm certain to have the perfect disappearing ring. Once I got an idea of how it mixed and reacted to the epoxy I went full in on a new project. I poured some TotalBoat epoxy in a knife handle blade to 90% full, let it kick for a bit, then mixed in Red-Clear @88 and drizzled it on top. I was totally blown away. It looks amazing... the red is so vibrant. I just eyeballed the amount to use and it came out great. Last I had a rainy Sunday project with my daughter. we poured some top coat nail polish into a cup and mixed in some pigments and did different nails. Then top-coated them in clear. The best temperature reaction I think is the Yellow-Red @59. Super fun and she loved the process. And according to their instructions, while you shouldn't eat the stuff, it is safe to handle. This stuff is awesome and I'm working on ways to incorporate all the color/temp combos in my work. It's going to be great to have different dimensions of effect that 'kick' at varying temperatures. Just need a truly-clear transparent! 🤣 But instead of that I'd do with a Red-Clear @77... ooooh.. or Clear-Red@77! SCIENCE MAKE IT HAPPEN! Review: RED-YELLOW A Great Visual Effect for Slime! - This RED-YELLOW pigment works well for slime. The temperature of just your hands is enough to initiate the colour change from coral to orangey-yellow and yellow. If you use a cold jell pack on it you can change the colour from a coral to a deeper red. The visual effects were really good and the children enjoyed playing with the slime to make the colour change. Easy to blend into the glue when mixing. But expensive if you are just making slime at home, as one 10g jar can make one bigger batch of slime (2 bottles of 4oz of glue) or two smaller batches of slime (1 bottle of 4oz glue each batch). Great for school STEAM activities though, as schools would have an expense budget. The recipe I used was as follows: 1 4oz bottle white glue, 1/2 to 1 teaspoon baking soda, 2 teaspoons contact lense solution. The BLACK-PINK product wasn't good. The colour when mixed with white glue is dark purple. It doesn't seem to change colours with the heat of your hands when handled. Did not get it to go pink at all, perhaps it needs a stronger heat source? It changes to black when an ice pack is applied. Not a great visual as the disparity between the dark purple and the black is not great. Wouldn't recommend. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01MTX2DMM | | Best Sellers Rank | #48,988 in Arts, Crafts & Sewing ( See Top 100 in Arts, Crafts & Sewing ) #644 in Fabric Dyes | | Brand | Atlanta Chemical Engineering | | Brand Name | Atlanta Chemical Engineering | | Color | Yellow-Red 59F/15C | | Compatible Material | Leather, Plastic | | Customer Reviews | 4.4 out of 5 stars 1,124 Reviews | | Item Form | amorphous, gelatinous | | Item Weight | 0.02 Kilograms | | Manufacturer | Atlanta Chemical Engineering | | Manufacturer Part Number | 1234 | | Model Number | 1234 | | Number of Items | 1 | ## Product Details - **Brand:** Atlanta Chemical Engineering - **Color:** Yellow-Red 59F/15C - **Compatible Material:** Leather, Plastic - **Item Form:** amorphous, gelatinous - **Item Weight:** 0.02 Kilograms ## Images ![Temperature Activated Thermochromic Color Changing Pigment Perfect for Color Changing Slime (Yellow-Red 59F/15C) - Image 1](https://m.media-amazon.com/images/I/813oD5aJxuL.jpg) ![Temperature Activated Thermochromic Color Changing Pigment Perfect for Color Changing Slime (Yellow-Red 59F/15C) - Image 2](https://m.media-amazon.com/images/I/81gD+Ijw-PL.jpg) ![Temperature Activated Thermochromic Color Changing Pigment Perfect for Color Changing Slime (Yellow-Red 59F/15C) - Image 3](https://m.media-amazon.com/images/I/51rVoHzNRtL.jpg) ![Temperature Activated Thermochromic Color Changing Pigment Perfect for Color Changing Slime (Yellow-Red 59F/15C) - Image 4](https://m.media-amazon.com/images/I/61QaVfBvKCL.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Super reactive, deep color pigments *by F***. on January 20, 2020* I've bought the Yellow-Red @59, Red-Yellow @77, Black-Clear @77, Black-Pink @88, Red-Clear @88 and tried almost all of them.

After I came across a video of someone making their own powder I wanted to give it a shot. I took a chance with this product and mixed it with clear dip powder, after a couple experimental fake nails I got the consistency I wanted. This product went above my expectations and was a lot easier to use than I anticipated. ## Frequently Bought Together - Temperature Activated Thermochromic Color Changing Pigment Perfect for Color Changing Slime (Yellow-Red 59F/15C) - LET'S RESIN Thermochromic Pigment Powder Temperature Activated That Changes at 88°F-5 Colors Changing Powder for Nail Polish, Paint, Slime, Epoxy, Resin, Ink, Fabric Art, Casting-3 Gram Each - Sun Activated Photochromic Powder Pigment PINK changing to VIOLET-BLUE when exposed to UV Sun Light Perfect for Color Changing Slime Science Experiments Nails Resin Jewelry --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/42463041-temperature-activated-thermochromic-color-changing-pigment-perfect-for-color-changing](https://www.desertcart.hr/products/42463041-temperature-activated-thermochromic-color-changing-pigment-perfect-for-color-changing) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-20*
