Ehhhh...U buy and u dun know the colours meh???
Anyway, I think the colours as follows.
1) Blue Base with yellow/green dots
2) Blue Base with orange/pink dots
3) Blue Base with green/yellow/orange/pink dots
4) Green base with orange/pink dots
5) Blue base with orange dots and blue skirting
6) Yellow with blue skirting
As I mentioned in my previous post, nos 3, 4 and 5 are the nicest amongst those that you have chosen.
The way to choose a nice yuma is actually to look at them under natural sunlight or under 10K metal halids. The reason being that if a yuma has nice colours under natural sunlight, then it will look insane under atinic lights as the fluorence will show up. The exception may be green which may not look as great under atinic as under natural sunlight.
