Why (and when) a perceptual color space?
Most image processing is done using a device color space (most often sRGB), and most libraries and interfaces expose that color space. Even when an image editing tool or a standard (such as CSS) exposes other color spaces, it’s still most common to use the device color space. But for some use cases, a perceptual color space can give better results.
Basically
the central question of color theory is how colors (in the physical sense) are perceived. The trichromacy assumption basically groups colors into equivalence classes in a three-dimensional space, and display devices generally produce colors by mixing three additive primaries: the familiar red, green, and blue.
