I've been building a free tool - Palette Inspiration https://paletteinspiration.com/ \- that extracts palettes and color analysis from master paintings (Monet, Vermeer, Sargent, Van Gogh - 3,000+ artists). It started as a frustration with palette generators that all converge on the same five muted pastels, when painters spent centuries working out color relationships we mostly ignore.
Each of the 22,000 of paintings has its own page: the extracted palette plus analysis of value structure, chroma distribution, and temperature balance. There's also a quick builder where every suggested color comes from colors that actually co-occur with your picks in real paintings - empirical pairings, not color-theory formulas - and you can upload your own image to get the same analysis.
No paywall, no email capture. I built it solo and would genuinely like to hear what working designers think - especially whether the analysis breakdowns are useful or just noise. #art
