What ColorSpace is
ColorSpace is a free web tool that generates color harmonies from a physical marker collection. Choose a base marker and harmony type, and it calculates a palette from matching markers. Its interactive generator includes more than 300 LAB-measured Ohuhu Honolulu markers. Listed color models include Perceptual LAB, HSV Uniform, Traditional 12-Color, RYB Classical, Munsell, and Natural Harmony; harmony options include complementary, triadic, analogous, split-complementary, tetradic, and monochromatic. Users can upload marker databases in CSV, JSON, or Excel formats, with uploads advised to stay under 10 MB. Palettes can be exported as PNG or JSON, though JSON exports omit hex codes. The Color Matcher extracts colors from reference images and finds marker matches using LAB and Delta E 2000 calculations. Harmony colors can also be expanded into highlights, base colors, and shadows. Uploaded databases are stored locally in the browser session. In demo mode, edits last only for that session and database downloads are disabled. The site describes its audience as studios, schools, and hobby collectives.
