So, in the new year, I intend to start painting my collection of models after a long time of collecting: as much as I like building them, the ones that I've got already can't stay unpainted forever! I've already decided on a scheme for the Craftworld units - Altansar - based on a picture/the lore in the codex (plus, I like the idea of an army based around Maugan Ra), and thanks to the citadel app, I have an idea of the basic colours to use, given their similarity to the Dark Reaper colour scheme. (At this point, I'm still deciding what colours to do my Kabal/Cult, as I want to do a custom colour scheme for them.)
The only question I have regards the base spray: Do I use black or white for the undercoat? And is there any discernible difference in the end result between the two? I know black would probably be better for the Dark Reapers, but I'm not sure whether it would be too dark for the purple used by Craftworld Altansar (at least, based on the (few) images in the codex).
Any insight would be greatly appreciated.
