Color codes

HTML colors are constructed using a combination of three basic colors: red, green and blue. Each one of these colors can take a value from 0 to 255 and are represented in hexadecimal notation (00 to FF). Having said this, a color is composed by six characters and the two first ones represent the red value, the two second ones the green and the two third ones the blue. For example, the red color is constructed in HTML with FF for the red (the first two characters) and 00 for the rest: "FF0000".

Mixing these values will mix the colors, so you can make a yellow by mixing red and green (e.g., "FFFF00"), violet by mixing red and blue (e.g., "FF00FF") or cyan by mixing green and blue (e.g., "00FFFF"). This works exactly as a painter's palette.

The tone of the color can also be changed increasing (e.g., clearer violet "FF66FF") or decreasing (e.g., darker violet "AA00AA") the three values proportionally.
