You can use several different kinds of paint but the main factor involved is metal prep and a primer/adhesion promotor in order for ther paint to stick well because the aluminum is so "slick". Prep is super important here.

With mounting hardware,nuts/bolts etc the paint will be prone to chipping just from assembly. The anodizing is a much sounder idea since the coating is basically a "stain" (very thin film) rather than a material thats built up on the aluminum for a even coat.

Maybe looking into deanodizing and polishing the stock ones or look for aftermarket towers in a different color or as Simplechump said look into DIY anodizing but be careful !
