It’s a term. Light has color. Tungsten and daylight, remember the lesson from a few days back? Here’s another example. Color corrected for ambient lamp light the flowers look decidedly different. And, it is especially so because these are silk flowers. Maybe not silk, but realistic enough looking, I am recently impressed to feel they are no longer to be ignored. Oh, light? The light is the same. The camera corrected for the color difference between room lights and daylight, Photoshop in the camera if you will.
