OpusDesk Hub What this tool does
Generate five HSL-based color variations from a six-digit HEX color. The base RGB color is converted to rounded HSL values. Selected modes vary lightness/saturation or rotate hue by complementary, analogous, triadic or tetradic offsets, then convert each result back to HEX.
How to use Color Palette Generator
- Prepare the input. Enter a valid six-digit HEX base color.
- Run or configure the tool. Choose a palette mode.
- Check and use the output. Inspect the five swatches and separately test contrast before copying colors.
How this tool works
The base RGB color is converted to rounded HSL values. Selected modes vary lightness/saturation or rotate hue by complementary, analogous, triadic or tetradic offsets, then convert each result back to HEX.

Output: The five-color palette includes complementary cyan #00ffff.
Limits, assumptions and interpretation
A valid input is # followed by six hexadecimal digits; this is not a full CSS color parser.
- Harmony rules do not guarantee readable contrast, color-blind accessibility or suitable print reproduction.
- Rounding and lightness clamps can make some generated swatches similar. Test foreground/background pairs in their real layout.
