Methane and carbondioxide.
This question can be answered two ways, the first is that you are referring to the colour of the green house, in which case the house would be green. However If you are in fact referring to a "greenhouse" then the answer would be that a greenhouse is made of glass, therefore it has no colour other than the colour you can see through it
Watermelon. It starts green, then white, then red, the seeds(baby)

A greenhouse is made out of glass or at least some sort of translucent plastic. (This is a trick question since folks will likely say green bricks.)

The two greenhouse gasses are methane and carbon dioxide.
Green House Gasses, A.K.A. CO2 or Carbon Dioxide.
Methane, carbon dioxide
Yes. Venus has an atmosphere. The atmosphere is so thick and full of green-house gasses, we could not see the surface. The green-house gasses keep it very hot on the surface, as well.
many produce green-house gasses and are bad for the environment
China (APEX)
green house gasses are produced like carbon dioxide which is the most common one produced by cars
the warming of the the earth as the suns rays upon exit from the atmosphere being reflected down to earth because of green house gasses.

Indeed they are acting alike. The glass in a green house allows light to enter but reduces the amount of heat that leaves. Green houses gasses in the atmosphere have the same effect on the planet in general.
It's emits greenhouse gasses but it doesn't use any.
