Aspiring Ynnari player looking for druhkari advice!

I’m looking to expand my Aeldari into ynarri with the new codex, and am likely to want to start picking up some druhkari towards that goal.

What would you all recommend starting with for druhkari? - and for ynnari specifically, what are some lore friendly colour schemes that would fit well with a ynarri force?

Super appreciate any advice!

(Tagging as lore because partially asking for lore reasoning for colour schemes!)
