Frequently asked questions

How does lightening work?

We convert to HSL and add your percentage to the lightness channel, clamped between 0% and 100%, then convert back to HEX.

Does the hue change when I darken?

No. Only the lightness value changes, so the underlying hue and saturation stay the same for consistent tints and shades.

What is the difference between a tint and a shade?

A tint is a lighter version (more white), a shade is a darker version (more black). This tool produces both.
