The group colors are:
1) White
2) Red
3) Black
4) Yellow
5) Violet
The little mnemonic is "Why Run Backward You Varmint"

In each group, the pairs will be the group color combined with:

1) Blue
2) Orange
3) Green
4) Brown
5) Slate

So, pair 18 (pair 3 in group 3) would be Black-Green.  Pair 1 would be
Blue-White
Pair 25 would be Violet-Slate.

I don't know any mnemonic for the pair colors.

I hope this helps.  Any questions?
