Help changing tab colors
 

I believe that skin1.css is where I should change the colors of my store. However, I'm having the hardest time finding the line(s) where I change the following tab colors:

1) Top Menu (the 3 tabs on the upper right-hand of the screen, titled: home, shopping cart and contact us (I was able to change the "center" of the tabs (.Tab { background-color: fcdad5), however, there is still an ugly border of yellow around them and this is what I need help changing.

2) Center of the screen, "products" tab

These are currently an ugly yellow and blue respectively and I am hoping to change them to a soft pastel color (FCDAD5)

Any help would be greatly appreciated

Those are images. Have a look at the templates that contain them (top_menu.tpl, dialog.tpl) and you will see which ones.
