Silly Coloring Question.. I hope

Okay so I don’t do a ton of multicolor stuff but a friend wanted an oilers logo on something I was making for them. So I hacked my way through combining the objects and came up with this…

All seems well unless you look at the inner circles of the blue and orange areas ( the O and R ). For whatever reason I cannot seem to get the paintbucket tool to pick up these areas. I did also try to just use the paint brush tool and it picks up the area on top and on the surface below but I cannot seem to get it to recognize those circular areas ( perhaps because unlike the rest they have no ‘edge’? )

Anyway as the title suggests I am hoping this is just something silly I am missing so if anyone has any suggestions on how I might get this done I would really appreciate it.
