ActiveX Scrollbar Colors

I know you can change the BackColor and ForeColor of an ActiveX scrollbar in design mode, but it seems limited and wondering if that can be done dynamically as well?

I'm trying to show a scroll bar with a solid dark blue background and when I set this via the design mode, it almost looks like the background is 'checkered' and appears more light blue than dark blue.

I'm simply trying for a dark blue background, red thumb and 'ends' with a white arrows. It looks like the Foreground color controls the arrow color, but can't get a solid blue background with red thumb.
Thanks,
PT
