Improved Fluorescent Colors
The same principles of physics that apply to certain plant dyes of antiquity were used with Fluoro pigments, along with the addition of other stabilizers. It was successful to elevate the light fastness up to a "4" on the scale of 1 to 8. That's the same as Ultramarine Blue or Alizarin Crimson.
This product is superior to anything on the market as far as brilliance and resistance to fading.
