Color replacing

I have all of the plugin in white, but i cant find any color menu, or aleast in PHP/CSS/JSC. I just find out how to make a new color for the “menus buttons background”, but i cant find anything about white border, white dots between the texts, and the animation on point is too white.

So im just blind, or its not possible to replace colours

My my blog is a dark one 🙁
