ColorSpace
What it is
ColorSpace is a web tool for building color palettes around physical markers. Choose a base marker and a harmony type, and it calculates matching colors from the marker collection. The free interactive generator includes more than 300 LAB-measured Ohuhu Honolulu markers. Its listed color models are Perceptual LAB, HSV Uniform, Traditional 12-Color, RYB Classical, Munsell, and Natural Harmony; harmony options include complementary, triadic, analogous, split-complementary, tetradic, and monochromatic. You can upload your own marker database in CSV, JSON, or Excel format, with marker identifiers and color values. Palettes can be exported as PNG or JSON. A JSON export includes marker names and codes, the harmony type and color model, and tritone grouping, but not hex codes. Tritone expansion develops harmony colors into highlights, base colors, and shadows, with L* targets of 85 and 45 for highlights and shadows. The Color Matcher extracts colors from reference images and finds marker matches using LAB and Delta E 2000 calculations. ColorSpace describes its audience as studios, schools, and hobby collectives. Its companion ColorBase tool for photographing and measuring marker swatches is described as coming soon.
