color* the quality of an object or substance with respect to light reflected by the object, usually determined visually by measurement of hue, saturation, and brightness of the reflected light; saturation or chroma; hue.
hue* The property of colors by which they can be perceived as ranging from red through yellow, green, and blue, as determined by the dominant wavelength of the light. A particular gradation of color; a shade or tint or hue.
Considered the ideal light source, natural sunlight maintains a neutral balance between both the warm (yellow cast) and cool (blue cast) ends of the light spectrum. Northern light is the coolest, while light from a southern exposure is the strongest. Direct sunlight provides the "truest" rendition of colors in a room.
Natural sunlight is not consistent. It changes from sunrise to noon, to late afternoon and dusk. The intense golden rays and distinct shadows of a sunny, late afternoon can have a profound effect on the colors in a room.
Color rendition appears warm under incandescent and halogen lights. Reds and yellows are enhanced and blues and greens are culled. Under the cool cast of fluorescent lights, blues and greens are enhanced, while reds and yellows are muted.
The most important thing to remember is to always take the time to experience the paint color is every light.
Why do two colors, put one next to the other, sing? Can one really explain this?
