I have done extensive tests for lightfastness with these paints. Every color except magenta is light-fast. I have a piece that used even the magenta that was done 25 years ago. It has lived in sunny rooms and there is only moderate fading of magenta. The other colors are still perfect. I love the clarity of color with these paints. I reach for them often.

Prang is lightfast

I have done a full sun lightfastness test on these colors and all but magenta are unchanged after six months in a very bright south window. The black is my favorite black paint. These colors are brilliant, clear, and easily mixable.
