At its inception, CPSA realized that quality lightfast products would be crucial in gaining recognition for colored pencil as a fine art medium. Since 1991 CPSA has conducted its own ongoing colored pencil lightfastness testing. Results from these tests are made available in a workbook as a benefit to members of the society.
No matter what your artistic goals may be, it is devastating to think that all or parts of your artwork could disappear. And that is a real danger when artwork is exposed to light, particularly the UV rays in sunlight. Certain pigments may fade, change hue, or even disappear completely. The least stable colors are hot pinks, purples, blues, reds, and oranges, while browns, grays, and other neutrals generally remain unchanged. It will be worth your time to learn more about the lightfastness of the colored pencil products you use.
