Will this look good:

Suit - Skull White
Armour - Liche Purple
Trim - New Gold
Spikes - Honed Steel
Eyes - Knarloc Green
'Hair' - Gaveyard Earth
Gun - Honed Steel

This, as of now, is for the normal warriors.

I started painting the suits purple, and now I'm deciding to change scheme, so if I do decide to go with this will it matter if I paint over the purple with white, or what?

Much help/suggestion on colours is appreciated.
