Ever notice that in the bush after dark there is little to no radiant heat?? In fact its usually kind of cool. This is because the plant life absorbs the heat and transforms it in to work.
Painting surfaces green changes nothing. The object itself will still store massive amounts of heat. Man made objects don't turn the heat into something else. They just trap it and then release it slowly overnight.
I have a green belt in my backyard. We sit by the greenbelt at night to keep cool in the summer. When I approach my house from the greenbelt and can feel the heat coming off of the house. Not to mention the hot air trapped in the attic.
The object painted green would probably absorb less heat but would still trap much. My white.car retains its heat until at least midnight some nights.
We need more plant life in cities.

90% of of global warming is due to radiant heat. %7 is due to CO2 emissions from cars and factory's. Our atmosphere traps no more then 3% of the Sun's heat that encases the Earth.
Painting the street's and rooftops green or white means global warming = solved.
