Hex Color Codes
Hex color codes are made up of six characters, consisting of a hash sign (#) followed by six hexadecimal digits, like #00ff00. Hexadecimal is a base-16 number system that uses the digits 0-9 and the letters A-F. This allows each character to represent a value from 0 to 15. With six characters, hex codes can represent up to 16 million distinct colors.
The three pairs of characters in a hex code each represent the intensity of one of the three main colors used in on-screen colors:
| Character Pair | Color |
|---|---|
| First | Red |
| Second | Green |
| Third | Blue |
So in the hex code #00ff00, the color components break down like this:
| Color | Hex Value |
|---|---|
| Red | 00 |
| Green | FF |
| Blue | 00 |
The 00 red value indicates no red, while the FF green value indicates the maximum amount of green. With no blue, this makes #00ff00 a very bright, vivid shade of green.
RGB Color Model
Hex codes represent colors using the RGB or red, green, blue color model. This is an additive color model where mixing different levels of the three main colors of light produces all the colors we see on screens and devices.
The RGB values for a color can range from 00 to FF, or 0 to 255 in decimal. Each increment represents an increasing intensity of that color component. So #00ff00 in RGB terms is:
| Color | RGB Value |
|---|---|
| Red | 0 |
| Green | 255 |
| Blue | 0 |
By mixing the highest intensity green with no red or blue, this RGB combination produces the brightest possible shade of green.
