Frequently asked questions
Is every generated color guaranteed to pass text contrast?
No. HSL relationships coordinate colors but do not certify foreground/background contrast. Test actual pairs separately.
Will every mode reproduce the base color exactly?
No. The generator also adjusts lightness and applies a minimum saturation, so the selected base may change in a generated swatch.
