what does?

I'm not sure if this goes here, but what does a Hex Code mean? (for character groups)

Hexadecimal Color Generator

Hexadecimal colors codes are your ordinary decimal RGB (RGB) triplets converted into a hexadecimal triplet (#RRGGBB). They're most commonly used for web colors.

To expand upon that, hexadecimal [in all uses of the word] means "base 16" numbers. The common numerical system is "base 10," meaning you have 10 unique numbers before you start reusing them.
0 (the first unique number), 1, 2, 3, 4, 5, 6, 7, 8, 9 (the tenth unique number), 10 (a combination of 1 and 0), 11 (a combination of 1 and 1), etc.
In hexadecimal, you count to 16 before repeating:
0 (the first unique number), 1, 2, 3, 4, 5, 6, 7, 8, 9, a, b, c, d, e, f (the sixteenth unique number), 10 (the hex equivalent of 17 in base 10), 11, 12, 13, 14, 15, 16, 17, 18, 19, 1a, 1b, 1c, 1d, 1e, 1f, 20 (the hex equivalent of 32 in base 10)

Hex color codes use this base 16 number system to use numbers from 00 to FF, where FF is 255 in base 10.
So the colors are split up into Red, Green, and Blue, as shown in Bobby's post. The higher the hex value for the color, the more dominant the color.
FF0000 = red
00FF00 = green
0000FF = blue
And then you can mix the three to create different colors.

If you should ever want and need to capture a color you like you can use Color Cop to simplify matters.
