Simple ways to learn web designing colour codes

The colours are often represented by a 24bit code, in the RGB format. RGB stands for R=Red, G=Green, B=Blue, each of these 3 components is represented by a 8 bit value, it means you can give each component a value from 0 to 255, where 0 is no color and 255 the full-intensity. Remember RGB is an additive model, so all 0-value components means black, wherever all full'intensity components give you white. Usually the color values are written in hexadecimal format so you can see 6 digits ranging from 0 to F (A stands for 10, B=11,C=12,D=13,E=14,F=15). The first 2 digits represent the RED value, the second two represent the GREEN and the last two the BLUE. You can then combine the three components to get up to 16 million colors. Some examples: 000000= black FFFFFF= white FF0000= red 00FF00= green 0000FF= blue FFFF00= yellow FF00FF= magenta 00FFFF= cyan

well, as far as i can remember my computer science subject and engineering subject, the black is 000000 and white is ffffff the codes are 0, 1, 2, 3, 4, 5 ,6, 7, 8, 9,A, B, C, D, E, F. mix them all together and it will give a color.
