It's a bright, sunny day.
There are three hot-air balloons: black, white, and clear.
All other variables being the same, which would gain the most altitude?

I salute you, sir.

Black absorbs sunlight and heats up, while the white one reflects them. Both should feel a tiny amount of momentum on them. The transparent one won't, so the latter will win this battle.

Hot air balloons are lifted by the hot air. The black one absorbs sunlight and therefore has hotter air, making it expand further than the other 2.
Thus, black should win.

Brainlet here, wouldn't that also heat up the air around the balloon and make it float less? Or is that effect so small it wouldn't matter compared to the constant heating of interior air?

The black one radiates heat faster too though.

The hot air balloon is filled with a lot of hot CO2 which, according to hot theories, absorbes heat. Thus a clear ballon would allow the CO2 to absorb all the heat, causing a massive runaway process that heats the balloon immensely.
