I paint my space marines a dark purple with white trim, so I quite like the bottom picture. I'm not a very good painter, that being said, I base coat my minis in a light grey, then fold you I would suggest genstealer purple or kataphron purple depending on how dark you want the armour, emperors children, for the robes and pinkier armour plates. Use a darker purple thinned to a wash such as xerxes purple or the Army Painter brand purple tone wash, and fulgrim pink and dachala purple for high lights. As I said I'm not much of a painter but hopefully this puts you in the right direction
