About Huetone
Huetone is a browser-based tool for designing color palettes using the LCH color space. Because LCH models lightness the way people perceive it, colors at the same lightness level look equally light across hues, which makes a palette more predictable than one built in RGB or HSL.
That consistency helps when palettes need to meet accessibility contrast requirements across many hues and shades. It suits designers and developers building color systems for interfaces who want accessibility considered from the start.
Strengths
- Uses the perceptually based LCH color space
- Helps keep palettes accessible across hues
- Open source and runs in the browser
Limitations
- Assumes some familiarity with color spaces
- Aimed at palette building rather than quick color picking
