Understand HTML colours

Question

This section will explain how hexadecimal values are calculated.

Answer 1

Every colour is a combination of R, G, B that is Red Green and Blue. In rgb the colour ranges from 0-255. In hexadecimal form its 0-F that means #F00 stands for #RGB since Red position has Highest value and other colours have zero. #F00 stands for red. red can also be represented in #FF0000 and it follows #RRGGBB
Now how hexadecimal represents RGB values:
In #RRGGBB
The first R is multiplied by 16 that is 0 = 0, 1= 16, 2 = 32...F = 240
Second R represents actual value. That is 0 = 0, 1 = 1...F = 15. So #FF0000 is #240+15,0,0 = #255, 0, 0.
In short form that is #RGB its R * 16 + R. So #F00 is #15 * 16 + 15, 0, 0 = #255, 0, 0
