The Nineteenth Hole

Hi, I just got Windows Vista Home Premium. I was fiddling around with it and found that I could change the colors of the window borders and stuff by going to personalize options and changing it to several options (Graphite, Frost, Default, Blue, Red, Pink, and Teal, I think they were). A little bit later, my screen went blank for a minute and upon coming back, a balloon on my start bar thing said the color scheme has changed to Vista Basic or something. The colors all changed. I really wanna change them back but when I click on the same stuff to open up the colors I could choose from, it goes to this window called Appearance Settings. I can choose from Aero, Vista Basic, High Contrast, Windows Classic, and a couple others. These are not what they were. I changed it to Aero, it looked the same, but when i went to change it again, it said I was still on Vista Basic. Does anyone know how I can get back to Graphite??
