What this tool helps you do
Explore related colors for an interface or illustration by rotating the base color’s hue while keeping its saturation and lightness. Choose a harmony and inspect the swatches alongside the generated HEX values and CSS custom properties. The original base color is retained exactly for its zero-degree position instead of being replaced by a rounded approximation.
Format rules and limitations
This uses the HSL color model and simple hue relationships, not a perceptually uniform color space or a trained design recommendation. Gray, white and black have no meaningful chromatic hue, so some results can repeat. A harmonious palette is not automatically readable or accessible: check foreground/background combinations with the contrast tool. The generator runs locally, accepts six-digit HEX input and does not change an uploaded image.
