It is confusing. You are trying to replicate digital painting (which is displayed on screens) with traditional mediums, on canvas/paper and you are asking what colors to use?
I mean sure colors matter, but isnt it more of an artstyle thing? I wont get too deep in the mud cause i don't know enough to advise you.
Only person here that i think could help you.
