UV Light Sensitive Color Changing Specialty Ink

Photopia® is a reversible color-changing material that in the presence of sunlight or ultraviolet light changes to a new color.

yellow, blue, purple, white, and black; no other colors please.

This logo is going to be for light sensitive color changing ink. Photopia is what the logo should contain and somewhere in small texts, I want there to be a 2-4 word description that clearly describes what this ink does or if you design a logo that clearly depicts the function of the ink, that is fine as well. I referred to it as light sensitive color changing ink, but if you can, come up with a description thats more clearly defined than the one I've stated.

Below is a youtube link I’ve provided of an example of a product that uses our light sensitive ink so you guys can get a better picture of how our product works.

I want this design to still look very modern so I’m also open to new ideas and suggestions, but most importantly try to do a design that reflects how its a temperature sensitive color changing ink.
