background of the program itself

[path]

Sorry I don't know how to ask this properly, but the background of the whole everything, before I even try to do everything, is black and it's really difficult for me to read. Is there a way to change it so the text and icons and stuff are black on white, instead?
Sorry if this is repetitious, but I didn't know the correct term to search for.
