I just installed the latest AbanteCart Cart and was wondering if I can change any of the colors in the default theme?  Specifically, i want to change:

1) the blue borders to a different color
2) the oragne in the block menus like "Categories"
3) two menus:  the one that has "Special offers, bookmark, etc" on the top, and the bottom menu that has "Home, Login, Account, etc"
4) background color

Thanks!
