Preparing color database
Create beautiful Ohuhu color palettes with our free interactive palette generator. Discover the ultimate tool for building harmonious Ohuhu color palettes -- browse 300+ LAB-measured Ohuhu Honolulu markers and instantly generate professional color combinations using complementary, triadic, analogous, and other color theory relationships. Every Ohuhu marker color is measured from real physical swatches, ensuring your Ohuhu color palettes are perfectly accurate for your artwork.
Every color is LAB-measured from physical swatches for perceptually accurate digital representation. LAB color space matches human vision, ensuring harmonies that look as good in reality as they do on screen.
Generate complementary, triadic, analogous, split-complementary, tetradic, and monochromatic harmonies using perceptual LAB calculations. Switch between multiple color theory models to find the perfect combination.
ColorSpace works with any art supply database. Currently featuring 300+ Ohuhu Honolulu markers. Upload your own marker collections to build custom databases with any brand--Copic, Prismacolor, or your complete studio inventory.
Explore all available markers organized by brand and set. Use the search bar to find specific markers by name or code, or filter by color family to narrow down your selection.
Click on any marker to use it as the foundation for your color palette. ColorSpace will automatically generate harmonious marker combinations based on the selected color theory model.
View your palette with complementary, triadic, or other harmony types. Switch between color theory models (LAB, HSV, Traditional, RYB, Munsell) to see how different mathematical frameworks affect harmony generation. Export your palette for reference in your artwork.

9 min readClick any Ohuhu marker from the collection to instantly generate harmonious color palettes. ColorSpace creates complementary, triadic, analogous, split-complementary, tetradic, and monochromatic combinations using your selected Ohuhu marker as the base color.
Use the search bar at the top to find markers by name, code, or brand. You can also filter by color family (reds, blues, greens, etc.) or filter by specific Ohuhu sets to narrow down your selection.
ColorSpace supports six harmony types: Complementary (opposite colors), Triadic (three evenly spaced colors), Analogous (adjacent colors), Split-Complementary, Tetradic (four colors), and Monochromatic (single hue variations). Each harmony type creates different moods and color relationships.
Click the sort button to organize markers by Munsell notation (color theory order), alphabetical by name or code, or by brand. You can also sort by lightness (L), chroma (C), or hue (H) values, with options for ascending or descending order.
After selecting a marker, use the MODEL dropdown in the palette viewer to switch between Perceptual LAB, HSV Uniform, Traditional 12-Color, RYB Classical, Munsell, and Natural Harmony models. Each model uses different mathematical frameworks to calculate color relationships.
ColorSpace automatically expands each base marker into a tritone (highlight, base, shadow). Highlights target L* 85 for lighter tones and shadows target L* 45 for darker shades, giving you ready-to-use color variations for shading and lighting effects.
All marker colors are LAB-measured from physical swatches using calibrated color capture systems. This ensures the digital representation closely matches the real-world marker performance. ColorSpace uses Delta E calculations to find the closest matching markers in your collection.
Yes! After generating a palette, you can export it as PNG for sharing or as JSON with marker names, codes (and new codes where available), harmony type, color theory model, and tritone grouping. We don’t include hex codes in exports to reduce bulk scraping, but the palette visuals still render accurately on screen.
Hue Lock preserves the color hue of your base marker while allowing variations in lightness and saturation for harmony suggestions. When enabled, all suggested markers maintain the same hue family, creating more cohesive palettes. Different color theory models implement Hue Lock differently - LAB uses perceptual hue constancy while HSV uses mathematical precision.
The Global Constraint Filter lets you restrict palette generation to only markers from specific sets. For example, you can limit suggestions to only Ohuhu Honolulu Pastels or Skin Tones sets. This ensures all harmony suggestions use markers from your preferred collection, making palettes more practical for your available supplies.
