Thanks for your reply.
Actually my .perlcriticrc has specific colors set for the various severity levels. I tried using --noprofile but still no colors appear. I also tried commenting out the color specifications in my profile (to get the defaults) and that didn't work either.
Comment on Re^2: perlcritic --color option not working
Take a look through the bug list. I didn't see anything related to color, but maybe you can get some debug tips. (Tip #11 from the Basic debugging checklist.)
