552048 Wordpress modifications 2

Hi, I need one little modification on my wordpress, an scriptlance's developer have already modified my WP but, I need a little modification. Each category have a color. Now when items are hovered, it's showing the color "Grey" (#313131) and when it's off, it's showing the category's color. I only need to inverse this ! 2nd, We have optimised the wp, with cache, minify... so now we have a trouble with this, when you hovered one time, the item keep one color, and only color for all items. I think it's due of the cache. See in attach file the php template, this file is duplicate many times so every modifications must be commented. It's a little modification, we're waitng for small price too ;) We hope find a developer for a long time relationship.
