What I understand from your question is the colour of the brake lights don't match. Correct? (Sorry the OP's question is not clear).
If you haven't replaced the brake lights or the bulbs, then you can take it to a dealership for an inspection/troubleshooting. If you replaced a blub, if it the correct type, then you can replace the other one with the same blub (same manufacture).
