RGB colors made simple.RGB is not a complicated scientific term, it means RED GREEN BLUE. RGB colors are described by a (on SVGA or larger displays) six digit number each of the three colors being two of the digits - rrggbb. so the number 862007 would be a basically red color (86 = red 20=green 07 = blue) The numbers are in base 16 ( which is also called hexidecimal). Base 16 is also simple to learn.First, in base 10 376 = (3 x 10 x 10) + (7 x 10) + 6 with RGB colors, every color is discribed as a two digit number in base 16: 76base 16 = (7 x 16) + 6 = 118base 10 In base 16 the digits 0 - 9 are the same as base 10, but they needed to add digits for 10 - 15, so:
Base 10 Base 16
0 - 9 = 0 - 9
a = 10
b = 11
c = 12
d = 13
e = 14
f = 15
So bdbase 16 = b x 16 + d = 11 x 16 + 14 = 190base 10 The highest 2 digit base 16 number is ff = 255base 10 so 00 is no color , ff is total color. because the color monitor uses light adding more makes color lighter. |
| 00000 is the absence of color - black. |
| ffffff is the presence of all color - white. |
| ff0000 is red. |
| 00ff00 is green. |
| 00ff00 is blue. |
| ffff00 is yellow. |
| ff00ff is fushia. |
| 00ffff is cyan. |
| and intermediate values give other colors: |
| b00000 is maroon. |
| 990000 is a darker maroon. |
| ff4040 is pink. |
| ff8080 is paler pink. |
| ffb0b0 is a paler pink. |
