I am over the moon with my colour choice. No available colour i'd rather have. Looks good in all light, doesn't look filthy or dusty immediately.
If the metallic blue you are referring to is night blue, then it is one of those colours that looks amazing in some lighting and not so good in others. I'd have given consideration to something like "Rising blue" on my Roc, or the old R32 blue (which i'm sure will be back for the "R").
