My idea is still to use a template:
colorFromString!"rgba" or colorFromString!"argb" (please notice 
that AFAIK, the second most used way is actually "abgr" rather 
than "argb" - because of byte-order)

And I think it's a good idea to set template argument to some 
default.

MS is not sure about this, anyway.

OpenGL use rgba (and abgr?) directX argb:
