Most of the world's most valuable paintings and drawings are kept in the dark, with a recommended display period of not more than 6 weeks every 2 years. Why? Because the UV light in everyday life damages them gradually, fading their colors and stripping them of their lush palettes. This study asks how different colors affect the rate at which UV light bleaches a piece of paper. We tested different architects' stock colors under a UV torch for hours, controlling most other possible variables, and our results reflect the difference in RGB values shown by these colors. Through this, we see trends - the larger the R/G/B value, the larger the change that occurs to it. .Picture
ABSTRACT
Most of the world's most valuable paintings and drawings are kept in the dark, with a recommended display period of not more than 6 weeks every 2 years. Why? Because the UV light in everyday life damages them gradually, fading their colors and stripping them of their lush palettes. This study asks how different colors affect the rate at which UV light bleaches a piece of paper. We tested different architects' stock colors under a UV torch for hours, controlling most other possible variables, and our results reflect the difference in RGB values shown by these colors. Through this, we see trends - the larger the R/G/B value, the larger the change that occurs to it. .

This experiment is built on the 255/255/255 value RGB system. In this system, a color has 3 values, representing the ratio of red to green to blue pigment - hence its name, RGB. A color with 0/0/0 is black and a color with 255/255/255 is white. 255/0/0 is red, 0/255/0 is green and 0/0/255 is blue.

The larger the value, the lighter the color.
