Backgrounds are so difficult - I need some input

I recently was paging through an old cooking magazine and saw an article about quinces, a cross between an apple and a pear.  I used the article as an inspiration for a study of quinces (which I think came out quite well) but now I have a dilemma - what to do about a background?

Should I just add some shadows and leave it white?

Should I paint a background - solid or varigated, one color or multi, and what color(s)?

I looked on the color wheel and the compliment of yellow green is magenta so perhaps a dark background - a magenta black combo) would make the quinces really pop but then again.....

What do you think? I would truly appreciate your thoughts.
