I will try to give the best advice based on your post. Have you started any sort of treatment or recovery program? You can only get so much advice from the community without it possibly leading to compulsion seeking. The best thing you can do at the moment is sit through the anxiety you're having and use this as a challenge to do something different with your obsessions. ERP is going to be the best form of therapy, but it is better to get a proper diagnosis and work with a specialist on a good recovery system. You can call into NOCD and set up an appointment! In the mean time, be very easy on yourself and try your best to avoid compulsions! When your OCD starts telling you to focus on the colors, allow yourself to remember that they're just colors. You don't need to avoid them!
