I ran git bisect and the problem was introduced in #5284 and is still present in current HEAD (765de7b).
The problem only occurs when colour is registered into the store, if you cabal get colour and then try to build that package as an inplace package it works fine.
I tried playing with verbose options but haven’t managed to get any useful info out of this so far.
The colour package doesn’t seem to use any globs and cabal check is happy, so this looks like a bug in cabal (rather than a bug in the cabal file of colour).
