The record

Purpose: ColorSpace generates color harmonies from a user’s physical marker collection.
How it works: Users choose a base marker and harmony type, then ColorSpace calculates a palette from matching markers.
Color models: The marker collection page lists Perceptual LAB, HSV Uniform, Traditional 12-Color, RYB Classical, Munsell, and Natural Harmony models.
Harmony types: The marker collection page lists complementary, triadic, analogous, split-complementary, tetradic, and monochromatic harmonies.
Marker library: The site says its free interactive generator includes 300+ LAB-measured Ohuhu Honolulu markers.
Custom collections: Users can upload marker databases; the upload page describes CSV, JSON, and Excel formats and required marker identifiers and color values.
Palette export: Palettes can be exported as PNG or JSON; the site says JSON exports omit hex codes.
Tritone expansion: The site describes expanding harmony colors into highlights, base colors, and shadows, with highlight and shadow targets of L* 85 and L* 45.
Color matcher: The Color Matcher page says it extracts colors from reference images and finds marker matches using LAB and Delta E 2000 calculations.
ColorBase availability: The home page labels database building as coming soon, and the upload page says ColorBase will be available soon for creating professional databases.
Privacy and security: The privacy policy lists encryption in transit and at rest, regular security assessments and updates, limited access to personal information, and secure hosting infrastructure.
Data collection: The privacy policy says ColorSpace collects usage and device information as well as color data and palettes users create or upload, and uses Google Analytics and Google AdSense.
Audience: The About page describes ColorSpace as serving studios, schools, and hobby collectives.
Free access: The marker collection page calls its interactive palette generator free.
