I think with color, it’s important to appreciate the irregularity that exists in this domain. You’re right that colors are defined as ranges of wavelengths or blends of ranges of wavelengths. And so there is a mathematical component to color. Yet, the mathematical view of color is imperfect if you ultimately are concerned with the perceptual end result. People are always trying to create better, more perceptually accurate color spaces, but all of them have their issues and weird corners where the adjusting the values in a certain direction doesn’t yield the expected result.
