How it works:  For each color, FF is the full saturation for that color, and 00 is the least.  Black (#000000) is the absence of all the colors, but when all the colors are put to their full saturation (#FFFFFF) it produces white.  each color is written with the red value first, then blue and green.  It's like plotting the values for each color in the table above into an rrggbb format.  Red would be full saturation of red, and none of the rest (#FF0000).  Green would be full saturation of green, and none of the rest (#00FF00).  Blue would be full saturation of blue, and none of the rest (#0000FF).  Then, we come to Purple.  We all know that red and blue make purple, so we use full saturation of both of those colors (#FF00FF).  This code produces a dark, almost unrecognizable shade of purple, so you want to lighten it by using the same saturation for both colors, but lower values (#990099).  You can do this to lighten a plain color such as red too (#CC0000).
Note: #00FF00 produces a bright neon green, instead of a normal hue.
