Menu Buttons Different Colors

Good day,

Need some advise, want to use the theme to create a children’s website.

I need to be able for each menu item to have its own bright color. and the blocks a bit bigger.

There is no site yet i first want to see if i can recreate the look if not then i have to buy the theme that i am trying to recreate.

And maybe different buttons for the woocomerce products as wel.

Many thanks

Ps: Here is a Hair Salon demo i did with your theme: http://hair.mycoolsite.co.za/
