Homebrewfilter: why do clear bottles carbonate the beer better?

My wife makes her own homebrew, which I happily consume. We've noticed that the beer which is bottled in clear bottles will become more carbonated and have a better head than that in green bottles (and brown bottles, I think, though I wouldn't swear to it). This seems strange to me, especially considering that the bottled beer is supposed to be kept out of the sunlight anyway (we keep it in a dark cupboard).
Does anyone have a chemical explanation of what's going on? In terms of the amount of sugar added before bottling, how fine is the line between the green bottles turning out too flat and the clear bottles exploding? More generally, how can we acheive a uniform carbonation, or at least minimize the amount of beer that ends up flat-ish?
