The victory to a while, I used vallejo Green-Grey number 886 over a black undercoat, I blend drybrush and highlight depending on the model. The main problem with the Victory was the sheer size and weight. I guess it took around a day and a half.
The White Stars are painted using Rackhams paints, Abyssal Blue, Sacred Blue and whatever the purple one is that I can't find. They were painted with a lot of washes and wet blends over a whit undercoat then highlighted. It doesn't take long, maybe an evening for 3 ships, but wet blending is messy and you need to judge the timing of the next coat fairly finely or it all just merges into one colour.
