This goes back to the original sin of using RGB/sRGB to express natural colors. Nature doesn't work in terms of how much red, green and blue it needs to mix on the canvas. Sure, it's great and intuitive to represent colors on digital systems, but that's it. Light in nature works in terms of hue/tint along a continuous spectrum, brightness and saturation. Color spaces such as HSV/HSL model these concepts much better than any RGB algorithm, and doing math with them produces results that actually make mathematical sense. YUV also takes human color perception into account. It's not a coincidence that most of the smart lights usually use HSV/HSL color spaces, and most of the cameras opt for YUV* based color spaces.
