In HTML, hex colors are specified using the ‘#’ symbol followed by a six-digit hexadecimal number. The first two digits represent the red component, the next two digits represent the green component, and the last two digits represent the blue component of the color. For example, the hex code for pure red is #FF0000, where FF represents the maximum value of red and the other components are set to 0.
Here are some examples of popular hex colors:
- #FFFFFF – white
- #000000 – black
- #FF0000 – red
- #00FF00 – green
- #0000FF – blue
- #FFFF00 – yellow
- #FF00FF – magenta
- #00FFFF – cyan
You can also use shorthand notation for hex colors by reducing the six-digit code to a three-digit code if the two digits of each component are the same. For example, #FF0000 can be written as #F00.
