green!
Chlorophyll absorbs every color of the sunlight except for green. It is green and it cannot absorb its own color.
a leaf look green in sunlight as it has green colored pigment in it. When sunlight falls on it all other colors are absorbed by the leaf as sunlight forphotosynthesis and green color is reflected to our eyes and the leaf look green to us.
Green on hot days and Magenta on cold days
Depends on what portion of the sunlight it diffuses (reflects in all directions). If the roof is painted green, it will only reflect the green portion of the sunlight and so appear to be green. You can substitute yellow, blue, red, or any other color for "green" in the previous sentence.
if you meant color instead of green color it would be black
the green color of the leaf is due to the presence of plastids called chlorophyll not sunlight. this is d reason why they appear green even in the absence of sunlight.
green
If an object is white in sunlight it will be green in green light. A white object reflects all wavelengths (colors) of light that shine on it. If only green light shines on it, that color will be reflected and the object will look green.
