Frequently asked questions

What color formats does it show?

It shows HEX, RGB and HSL for each color so you can copy whichever your stylesheet uses.

What does the alpha channel control?

Alpha sets opacity. In 8-digit hex the last two characters, or the fourth value in rgba/hsla, range from fully transparent to fully opaque.

When should I use HSL over HEX?

HSL is easier to tweak by hand because you adjust hue, saturation and lightness independently, which is great for building tints and shades.

Are named colors and hex interchangeable?

Standard CSS named colors map to fixed hex values, but only a few hundred names exist, so hex gives you the full range.

How do I pick an accessible text color?

Aim for a contrast ratio of at least 4.5:1 against the background for normal text. Use a dedicated contrast checker to confirm.

Is any data uploaded?

No. Everything runs locally in your browser.
