I wanted to post these for people who need some simple ideas on how to paint their rebel fighters. I used Games Workshop Dheneb Stone for the base color except for the B-wings which used Celestra Grey.
A wings: I used Privateer Press Skorne Red for the red paint. I'm very happy with how they turned out. These were the most fun to paint.
Y wings: To me, Y-wings look more worn out and battle damaged than other squadrons do so I used a light black wash with grey highlights in the middle section. Also, the yellow I had was too bright so I mixed it with a little bit of tan so they don't look factory new. Star Wars is gritty after all.
B wings: These were the most difficult to figure out how to paint. In the movies, they just look grey so that's what I did with them. I added some dark blue stripes on them but I might need some inspiration ideas to make the B-wings stand out more.
