How Color picker works

Pick a color with your browser's color control or type a value, and the tool returns the hex code, the CSS rgb() string and the three red, green and blue channel numbers from 0 to 255. You can enter a 6 digit hex code such as #3366cc, a 3 digit shorthand such as #f80, or three numbers like 255, 136, 0. It works with hex and RGB values only: named colors, HSL, and alpha values such as rgba() or 8 digit hex are not accepted.

Before you start

Have the color in hex or as three whole RGB numbers from 0 to 255. If you only have an HSL or named color, convert it first or pick it visually with the color control.

A worked example

Typing the shorthand #f80 returns hex #ff8800, rgb(255, 136, 0) and channels 255, 136, 0. Entering rgb(51, 102, 204) returns #3366cc.

Common questions

How do I convert a hex color to RGB?

Split the six hex digits into three pairs and read each pair as a base 16 number. For #3366cc, 33 is 51, 66 is 102 and cc is 204, giving rgb(51, 102, 204). Type the hex code here and the tool shows the result immediately.

What does a 3 digit hex code like #f80 mean?

It is shorthand where each digit is doubled. #f80 expands to #ff8800, which is rgb(255, 136, 0). The tool expands shorthand codes for you and always shows the full 6 digit lowercase form.

Why does my color value show an error?

The tool accepts #RGB, #RRGGBB, or three whole numbers from 0 to 255 separated by commas or spaces, optionally wrapped in rgb(). It rejects color names like red, HSL values, decimals, and transparency such as rgba() with a fourth value or 8 digit hex codes.

Will the color look the same on every screen?

No. The hex and RGB numbers stay the same, but display calibration, color management and lighting change how a color appears. Check important brand or print colors on the devices and media where they will actually be used.
