A few things worth knowing

How does this tool calculate its result?

Analogous spreads hues from −60° to +60°. Complementary alternates opposite hues; triadic cycles 120° apart. Additional cycles lighten variants. Monochrome varies lightness at one hue. Values are rounded to 8-bit sRGB hex.

What assumptions and limits apply?

Changing the seed updates hue, saturation and lightness. Unlocked colors regenerate; locked positions retain their hex values. Schemes are HSL-based suggestions, not perceptually uniform or automatically accessible palettes. Monochrome uses a fixed 10–90% lightness range.
