This is really cool! I'm a painter and have spent a long time doing gamut analysis of paintings.
Thank you for including both HSV and HSL. Not enough people appear to understand/care about the difference between the two, and for painters the distinction is everything.
- pygy_ 9y agoWhy is the distinction important for painters?
- discreditable 9y agoI'd guess it's because mixing colors in paint is subtractive—if you mix every color you get black. Whereas with light, mixing colors is additive—if you mix every color you get white. In HSL, fully saturated colors have .5 brightness, and adding white or black changes the brightness but not the saturation. My guess is that works more similarly to paint than HSV does.
- kqr 9y agoLab too! I'm a digital photographer and operations in Lab space is both integral to my work and once you get used to it, it's very intuitive.
- jacobolus 9y agoBoth are absolutely terrible for painting (or any other human purpose, especially things like this scatterplot), and should be replaced with some perceptually relevant model. (Disclaimer: I largely wrote the wikipedia article about HSL and HSV, years ago.)
