What is the difference between HEX and RGB?

Both represent the same color. HEX uses a six-digit hexadecimal code like #3B82F6, while RGB uses three decimal channels like rgb(59, 130, 246).

When should I use HSL instead of HEX?

HSL is useful when you need to adjust lightness or saturation programmatically, such as generating hover states or theme variations.

Do I need the # symbol in HEX codes?

In CSS you typically include the hash, for example #3B82F6. This tool accepts input with or without it and copies the format you need.

Can I convert shorthand HEX like #FFF?

Yes. Three-digit shorthand HEX values expand to six digits before conversion, so #FFF becomes #FFFFFF.

Is color data sent to a server?

No. Conversions and preview rendering happen entirely in your browser.

What is a Color Converter?

A color converter translates the same color between web formats — HEX, RGB, and HSL — so you can use the right syntax in CSS, design tools, and JavaScript without manual math.

For example, the Tailwind blue #3B82F6 is the same color as rgb(59, 130, 246) and hsl(217, 91%, 60%).

How to Use This Color Converter

Enter a color in HEX, RGB, or HSL format — or use the color picker.
Watch the live preview update as you type.
Copy the converted value in whichever format your project needs.
Adjust HSL values to create lighter or darker variants for hover states and themes.

Worked Example

Your designer sends #10B981 but your CSS-in-JS setup expects RGB:

HEX input

#10B981

RGB output

rgb(16, 185, 129)

HSL output

hsl(160, 84%, 39%)

🌈 HSL

Intuitive for creating color variations and themes.

Frequently Asked Questions

Which format should I use in CSS?

All three are valid in modern CSS. HEX is compact, RGB is explicit, and HSL is easiest when you need to adjust lightness or saturation programmatically.
