Whether front or backlit, the temperature of lighting will change the way colors are viewed. The Kelvin measurement, also known as color temperature, is an important consideration in selecting lighting and applying it to your environment. Imagine a grey, translucent fabric over a light source. Lighting will transfer the color of this textile from a cool grey to a warm, almost beige shade of grey just by adjusting the Kelvins. The same rings true for printed colors; while a vibrant yellow print may be spot-on with color prior to lighting, adding a high Kelvin temperature bulb can muddy it up while a lower temperature bulb can pump up the richness.
