some people are always pencilers, some people are always colourists, some people are always inkers. Some people always do all three, and some people do two but not one.

It's just a thing I have learned to know over time, but the DC website usually has the penciler and inker listed. The interior credits will usually have everyone involved listed in order of penciler, inker, then colourist. If only two are listed, the second one is probably the colourist.
