Still using this wonderuull script.

I’m trying to add my own colors to the signup form.
The background was no problem at all.. fixed that within the stylesheet and index page.

Next I wanted to change the area where my customers can select a package.
The basic color of the border en the hoover is blue.

I want the border to be a different color.  (purple or aqua)

I have search the stylesheet but I can not find it.   It really does not match my current website at this moment…

Can you please help me to tell me where I can find it in the stylesheet ?
