Decimal vs Hexidecimal|
Converting from Hex to RGB
In HTML the Color Values must be specified in the hexadecimal system. |
Every value can also be expressed as decimal or hexadecimal in some color tools. In the decimal system the base is 10, in hexadecimal 16.

Quickie Color Converter Estimation:
You'll get very close to the original hue, using these 2 methods. If you're not quite satisfied with what you get--too dark or too blue, or whatever, then try adjusting the individual color codes until you get about what you wanted.
HEX codes have 16 steps: 0-9, a (10), b (11), c (12), d (13), e (14), f (15)
RGB: 0-255 steps
255 divided by 15 steps = 17
17 (RGB) = ONE hex step.
Method 1: HEX to RGB:
Example A: ff 66 33 = 255-102-51
RED: ff = just use 255 in the red box.
GREEN: 6 X 17 = 102
BLUE: 3 X 17 = 51
Example B: 33 cc ff = 51-204-255
RED: 3 X 17 = 51
GREEN: 12 X 17 = 204
BLUE: ff = 255
Method 2: fc ed 99 = 229-229-153
RED: fc. f = 15; c = 12. Split the diference = 13.5 RED: 13.5 X 17 = 229
GREEN: ed. e = 14; d = 13. Split the difference 13.5 GREEN: 13.5 X 17 = 229
BLUE: 9 X 17 = 153
When the hex code of a hue is closely split between 2 values, then split the difference on the hex code scale. Or if the difference is really great, then just use the first hex numeral/letter, as that's the stronger channel.
To convert from the RGB code to the hex code:
Just divide whatever number is showing for each of the values by 17. Then use the chart above.
