However, it's adviced against using color as a primary indicator, which is not relevant here because the primary information is conveyed via item background, but color is always a tricky thing. For instance you have to take color impaired people into consideration (~10% have issues with red/green). Be sure to have at least a good contrast between the page background color (blue in the bee theme) and the selection background (green) (color contrast checkers are a lot out there, for example http://snook.ca/technical/colour_contrast/colour.html).

Thank you for the link to the color contrast checker. I checked that the contrast Text/Item Background is high enough for all themes. Only for the diamond-flower theme the contrast is low, but this theme has a low contrast overall. The "Fluffy Bunny" theme has a pink background providing a low contrast between the wrong answer background an the page background. But I think this case is acceptable, because if a wrong answer is selected also the correct answer is highlighted and for this one, the green/pink contrast is good.

Instead of QRadioButtons, the new design uses QPushButtons and tweaks their appearance using Qt Style Sheets making sure that the design works with all themes available on Get Hot New Stuff. The results are displayed in the screenshots attached:
