Advice sought on painting Drukhari terrain

I'm getting some Drukhari terrain printed in anticipation of playing a Commorragh Crusade campaign, and was hoping for some ideas/advice on colours and effects that I could use in painting the terrain.

I don't own an airbrush, and I don't particularly want to do a lot of painting other than drybrushing, but I don't mind buying/using fancy rattle cans.

Grateful for any input.

I am pretty terrible at painting, so I keep it simple.

Start with a dark base, drybrush a medium colour that gets 85% of the model, drybrush a lighter-medium colour on 20% of it, then drybrush a light colour on 5%.

I like grey/green/purples. Maybe some bone.

Dont know if my amateur advice helps, best of luck buddy!
