HEX Value
- In HTML, a color can be specified using a hexadecimal value in the form: #rrggbb.
- Where rr (red), gg (green) and bb (blue) are hexadecimal values between 00 and ff (same as decimal 0-255).
- For example, #ff0000 is displayed as red, because red is set to its highest value (ff) and the others are set to the lowest value (00).
