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

I purchased it for my 14 years old daughter to make color changing slime. It tuned out amazing. Such bright colors and the changing effect works like magic. This powder is concentrated and a little goes a long way. We had left over and decided to mix it with clear nail polish - so cool! Very interesting how the nail polish changed to purple, not blue like the slime. I think there’s something in the polish that doesn’t let the sunlight to absorb 100%. The rest of the powder we mixed with clear glue for paint that changes color. We have a UV flash light and now my daughter can’t stop experimenting with it. So fun! I highly recommend this product!

My daughter used this to make slime, and it was incredible watching her discovery the color changing aspect in sunlight. It brings so much joy and excitement. I have mixed this with a pearlescent paint which we used for valentines gifts, and most recently I have begun experimenting with adding it into watercolor paints and paintings I have done. I love it and will definitely be buying more colors in the future.

It didn’t work as expected.You need to expose it for a long time. Following other customer advice,it start working fine .

This UV changing powder is PERFECT to use when making slime. We made slime and took it outside and the color change was instant. Very cool product if you want to make unique slime!

I use this product in a craft I make and sell at vendor events. This pigment changes to blue instantly as it is exposed to the sun. Since I am under a UV blocking tent, it's pink. I ask my customers to put it in the sun and their amazement to how quickly turns to blue is great!! It's always a huge seller for me. Since I can't be half inside/half outside for the picture, I used a UV flashlight on a section of the putty and you can very clearly see that it's blue after I take the flashlight away. I had to take the picture quickly because it goes back to pink within seconds! As with all pigments/micas, the more you use, the more dramatic results you will see. I have order multiple products from Atlanta Chemical and they have some of the best color-changing pigments on the market!!! The heat color-changers are amazing too!! I highly recommend this company!!

This powder was just what I was looking for, it works great.

Awesome! Works even better than expected. The color change is fast and the longer you keep it in the sun the darker it gets until it's a deep navy blue. But the moment you take it out of the sun it fades to a purple then pink.. pale pink again in around 10 seconds. We used this in our clear slime recipe, coolest slime around.

This product is strictly UV changing. Your hands won't trigger the color change. It's cool to show off to the kids though.
