What does lightfast mean?
The term 'lightfast' refers to the resistance of a material or color to fading or discoloration when exposed to light. This is particularly important in art, design, and textiles, where colors may be subjected to prolonged sunlight or artificial lighting. Lightfastness is often evaluated using standardized tests, such as the Blue Wool Scale. In general, lightfast materials and colors are those that retain their original hue and intensity over time, even when exposed to intense light.
