Almost all art fades given enough light and enough time. Some art media fade quicker than others. Watercolors and color photos are particularly susceptible to fading. Of course, the best way to protect your art and keep if from fading is to put it in a dark temperature and humidity-controlled vault. However, it is hard to enjoy your art under these conditions. Using conservation glass helps significantly to slow fading of your art by filtering out the ultraviolet part of the light. If you have light-sensitive art, you might consider displaying it in a place that does not have intense light. Bring your art in for an evaluation. We have UV-filtering glass and acrylic that will significantly help with your problem.
