I am useing a different theme, and I know I changed the color. I thing only certian themes can have their color changed, but I'm not sure.

To change the color, I think nyou go to the control panel and go to the bottom, where it says theme. Once again, I know that you can chage the theme color, but I did it a long time ago and I forgot how to. I hope that helps a little.

I think you can change the theme color by going to the menu in the home screen (the dropdown, with the button under the d pad). go to set background image and the first thing there asks you what color to set it.
