What does this tool do?

- See the result in the live preview.
- Copy the generated CSS/code into your project.
How the formats relate
HEX (#3B82F6) and RGB (rgb(59, 130, 246)) express the same color in different notations; both are built on red, green, and blue channels. HSL (hsl(217, 91%, 60%)) instead describes a color as hue, saturation, and lightness, which makes lightening or muting a shade intuitive. This tool bridges all three, so you can turn a HEX from your design file into the HSL you use in CSS.
Common use cases
It is handy for writing a HEX from Figma into a CSS variable as RGB, generating tints and shades programmatically with HSL, adapting brand-guide codes across different tools, and preparing rgba values for transparency. The live preview lets you confirm the numbers match the actual color you expect. Every conversion happens in your browser.
Frequently asked questions
What is the difference between HEX and RGB?
Both use the same RGB color model. HEX is a compact hexadecimal notation (#FF8800), while RGB shows each channel as a decimal value from 0 to 255. They are two notations for the same color.
When is HSL more useful?
HSL shines when you want to keep a color's hue and adjust only its lightness or saturation. That makes it far easier to build consistent light and dark variants and harmonious color palettes.
Can I convert alpha (transparency) values?
RGB and HSL support an alpha channel via the rgba() and hsla() formats, and the transparency value is preserved across conversions. In HEX it is expressed with the eight-digit #RRGGBBAA notation.
