How to change taskbar color...

I just recently got Windows 7, and I was fooling around with the customization, themes, etc.
When I first opened the customization menu, I was able to change my desktop background, as well as the color of the windows/taskbar. Originally, there was just a window that had a list of colors I could set the windows too, the colors were like Sky, Twilight, etc.
After fooling around more, I changed the theme of my computer, and I tried all of the basic themes, such as Classic, High Contrast, etc
Now, after doing this, when I tried to get back to the original screen I had to change the taskbar color, a different window came up, like the original window for changing colors that older versions of windows had, and I cannot seem to get back to the original screen for selecting colors. All I want back is the original black taskbar that Windows 7 comes with. It currently is just plain white.

I`ve checked around the site, and I do remember reading that after you changed the themes to basic, etc, that the original color window would not come up anymore.
My question is simply how do I get that window back to change my taskbar color back to black.

I hope you all understand what I am talking about, I tried my best to explain it.
Help would be appreciated, thank you.

You should be able to switch to one of the aero themes (1st pic) and then on the bottom click window color to get the (2nd pic) and change the color to what you want.
