https://medien.halowerk.com/v1/image-paletteOverview
Takes an image by URL or inline base64 and returns its colour palette: up to sixteen colours, each with the share of the visible area it covers, its HEX and sRGB values, its OKLCH coordinates, and the WCAG 2.1 contrast ratio against white, against black and against every other colour in the palette. The grouping runs in OKLab rather than RGB, because distance in RGB does not match what an eye sees — it merges dark blue with black and splits two yellows nobody tells apart.
