Well to be fair, the X-Wing kits have decals for every colored detail on the vehicle. I could have painted those patterns myself manually but I'm lazy the decals were pretty good substitutes and putting the decals on was faster to do than masking the patterns manually on the vehicles.
Both X-Wings have in-scale figures to go along with it. Here they were after painting:
The Clone Trooper kit, however, comes with no decals. And I didn't want to end up with a vanilla Clone Trooper so I had to mask those patterns to make it look like the Episode III white/blue Clone Trooper variants.
