I work with color professionally, every day since many years. How it behaves physically, how we perceive it, why certain combinations work and others don't. I wanted an app that understood all of that. Everything I found was either some hex-code picker or a palette generator. You could pick colors but never understand why and how they worked. And nobody seemed to be modeling what actually happens when pigments mix versus when light mixes: two opposite physical processes. So I built Chrooma. You can pull a palette from any photo and immediately see why those colors work together: which Itten contrasts are present, where the colors sit in Munsell space, what harmony type they form. Or go the other direction and mix your own colors with spectral calculations that model paint, light, and colorant as separate physical processes. There are 23 perception challenges that test how well you actually see. Not trivia. You're sorting value steps, matching illuminants, reconstructing palettes from memory. People discover things they didn't expect about their own eyes. Maybe sharp hue discrimination but mediocre value resolution, or color memory that holds for warm tones and disappears for cool ones. Your color Imprint evolves monthly, grounded in Goethe, Itten, and Bachelard. A curated Color of the Day and weekly palettes tied to seasons and cultural events keep things fresh. And 56 generative compositions let you turn any palette into shareable art. Photo extraction was the feature I almost left for v2. Glad I didn't. Pulling colors from a painting or a sunset and running them through the analysis is one of the best ways to learn why certain palettes feel right or off. Free to download with a lot of free content.
