Here is a litle saying I came up with to remember the second color sequence in a 25 pair cable:
When Roses Bloom You Vomit.
When = white
Roses = red
Bloom = black
You = yellow
Vomit = violet
You can also give a number to each color, with white being zero because it is not a real color. Then you can quickly translate the color code into a pair number using Mickey's formula:
Second no. times 5 plus first no. = pair no.
For instance if you have violet/green, then it is pair 23, because
4 x 5 + 3 = 23
