A different color for each menu tab

Hi all

Thanks for your amazing work here.

I need to find a way to put a different color on each of my menu tab.

If you were also kind enough to give me the code + where to put it for :
permanent state
selected state
hover state

website : www.monwe.fr

Thanks a lot.
I am selling this option right now, so I'll be glad to share some of it.

Thanks

Pierre
