HTML color code from a website

Colors are displayed combining RED, GREEN, and BLUE light.

Color Values

Colors are defined using a hexadecimal (hex) notation for the Red, Green, and Blue values (RGB).
The lowest value for each light source is 0 (hex 00). The highest value is 255 (hex FF).
Hex values are written as # followed by either three or six hex characters.
Three-digit notations (#rgb) are automatically converted to six digits (#rrggbb):
