Lighten a Color Online — Free
Runs 100% in your browser — your files never leave your device.
Hover states, disabled buttons, and layered backgrounds all need a lighter shade of a base color — and eyeballing percentages in a design tool is slow. Paste any HEX, RGB, or HSL value, drag the lighten slider, and copy the result in whichever format your project needs. The conversion runs entirely in your browser.

Copy the lightened color as HEX, RGB, or HSL with one click.
About this tool
How lightening works
The tool raises the lightness channel of your color in HSL space by the percentage you choose. Because lightness scales independently of hue and saturation, the color stays recognizably itself — a lightened brand red is still that red, just airier. The preview updates live as you drag.
When to reach for it
Hover states, disabled buttons, subtle backgrounds, and layered surfaces all call for lighter shades of one base color. Deriving them from the real value keeps a UI consistent; mixing white by hand in a design tool drifts and loses saturation in ways HSL lightening does not.
Tips for the best result
Hover states typically sit 8–12 percent lighter than the base; disabled states around 30–40 percent. If a lightened color looks washed out instead of airy, reduce saturation at the same time with the saturation tool.
Frequently asked questions
Which formats can I paste and copy?
Paste HEX, RGB, or HSL in any common notation, and copy the lightened result in any of the three. The tool normalizes whatever you enter.
Does lightening change the hue?
No — only the lightness channel moves. A lightened blue is the same blue; HSL shifts keep the color's identity intact, which is exactly why designers derive shades in HSL.
How much lighter should a hover state be?
Most design systems land between 8 and 12 percent. Stronger shifts suit large surfaces; buttons and links stay legible with subtler steps.
