What do you think about the various color combos? Which work and which are awkward? If you would, would you tell me if you agree or not with the ratings I've given. You'll notice the: Yes! / I'm not sure... / I'm thinking no...
(Black matches everything...)
(The non-primary colors can be tricky...)
(Purple and pink seem like no-nos)
(Might consider a darker, desaturated blue or a mat grey...)
BTW the layout for these guys is based on basically a merging of R2-R9 and ARC-170 Astromech (EU Clone Wars).
