Are your art supplies fugitive? I test a variety of pigment and dye found in watercolor paints, acrylics, inks, pens and pencils. Here are some of the results (find more, along with the before/after sun comparison images at www.KimCrick.com). This should give you a good idea if the art supply in question should be used in artwork for sale / hung on a wall, or if it will fade away over time. Please note that UV protective sprays and glass are ineffective against long term fading, but some thick applications of resin distort light enough to protect surfaces better.
