I see that the priority colors are not showing up as intended. 

Is this a new installation? You may need to clear your browser cache.

But if you are actually asking how to modify the colors to something of your own choosing, I would have to look into it. I can't quite recall but I don't think it is a simple answer.

Infelizmente as cores não são padronizadas, mas se você tem uma opção de mudar de cor, você poderia nos dizer como mudá-las?

Unfortunately the colors are not standardized, but if you have an option to change colors, could you tell us how to change them?
