For those specifying color characteristics of light sources, a few words of caution: While color temperature and CRI are important, the true complexities of a light source’s color characteristics cannot be captured with a few numbers, which is why there is no substitute for seeing the lamps in a given application. A separate mockup with [...]
Light is actually made up of colors. For an object to be perceived a certain color, that color must be present both in the object and the light striking it.
