What ColorSpace is

ColorSpace is a free web tool for finding color harmonies that match 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 format; the upload checklist says to keep files under 10 MB. Palettes can be exported as PNG or JSON. JSON includes marker names and codes, harmony type, color model, and tritone grouping, but not hex codes. ColorSpace can expand harmony colors into highlights, base colors, and shadows, with target lightness values of L* 85 and L* 45 for highlights and shadows. Its Color Matcher extracts colors from reference images and finds marker matches using LAB and Delta E 2000 calculations. The site describes its audience as studios, schools, and hobby collectives. ColorBase, a companion tool for photographing and measuring marker swatches, is described as coming soon. The service is supported by advertising, and the privacy policy describes collection of usage, device, and user-created or uploaded color data.
