Invisible scrollbars and GNOME Color Chooser

I have the following themes installed:

Controls: Clearlooks-DarkOrange

Window Border: ThinMC

This makes for a nice style, but the scrollbar button becomes impotent: it cannot be seen. (Usually with browsers.)

Some of you may have the same problem. You want to find the scrollbar button, but it cannot be seen.

Before: How not to be seen.

This is a scrollbar button. It cannot be seen. When you hover your pointer over the scrollbar button, it changes color... barely.

Why not just poke our eyes out and put us in a wrist lock? The result is the same: you won't be able to see and use the scrollbar button.

After: Now, when you hover your mouse pointer over the scrollbar button, it can be seen.
