So over a year ago, I was stuck on this idea of being able to visualize a full color space and travel within that space to build ‘chains’ of colors (like a 3D map with connected points). As a visual thinker, this made more sense to me than picking out individual swatches on a 2D color picker.
Part way into the research stage, I discovered OKLCH, which was a game-changer; it maps the colors around human visual perception, rather than how monitors mix light.
Up until now this has existed as a web app at www.volumecolor.io, but I recently ported it for use right inside Figma.
