Cant change Start+Theme

[Roofman99]

I have had a Nokia Lumia for almost a month, and am still getting used to it. A few days ago I obviously did something that has upset my Home (start) screen view. each square icon has a black background and I can't change it. The main background I can only select Black or White from within Settings> start+themes. I have selected a Photo, but it does not display at all. Any help will be appreciated.

Go to Settings-Ease Of Access, and disable High Contrast

Thanks Alexander, that's solved the problem, all the squares now have various colours, (as it was when new). I have now discovered what the > settings >Navigation bar settings do as well, I can't recall what the original setting was so will play around till I get the best one of the three options. Many thanks. A great result from my first posting.
