Changing the color of the voting panels in DarkRP

I have had this question for quite a while and I have searched quite a while in the DarkRP modules and I just can’t find where the colors of the vote and lottery panels are.
If anyone could tell me that would be great!

Take a screenshot and color pick it in a painting software.

Yeah thanks that was a very helpful response -_-

Sorry for the very helpful response.
So i found this in the dermaskins.png file :

The black squares is the voting bar and the blue squares are the buttons; There’s also a fade in square which is probably used for shading the buttons.
