That was on purpose, the main theme color is RED, the username was made light to shift focus on the problem title instead of users to add friction towards votes biased towards users.
When the users are logged in, the voting buttons get RED and you'll notice less of the pink(Please do give it a try and let me know if it's better).
Please excuse the plug(feedback is welcomed)
