The Lower the numbers, the darker the colors.
I know YOU COULD USE THAT COLOR PANEL ON THE SIDE OF YOUR POSTING PAGE, but yeah... I sometimes wanted to experiment on shades.

This is pointless.

Your chart is off by one.
0 = 0
1 = 1
2 = 2
3 = 3
4 = 4
5 = 5
6 = 6
7 = 7
8 = 8
9 = 9
10 = A
11 = B
12 = C
13 = D
14 = E
15 = F

FF = 256

Reading from right to left, the first number is your ones. The second is your 16's. You multiply the second number by 16 and then add the first to convert a number from base 16 to base 10.
