Well there are many pigments other than chlorophyll, and the light which is reflected is the actual colour of the pigment in a leaf. The light which is reflected by the chlorophyll appears green as it is the colour of the chlorophyll. Chlorophyll usually needs blue and red colour from the sunlight and it reflects the other colors.

"Greenlight" is either one word or two words as in : "green light", with different meanings.
"Greenlight" in English sentences means that a green signal or a positive nod or approval is given for performing some activity. The proposal (project) is given greenlight. It means that the proposal is accepted and OKAYed for proceeding further.
Green light in Physics (optics, optoelectronics) is the electromagnetic radiation in the range of 510 to 560 nm wavelength. Greenlight is one of the three fundamental colors of the white light spectrum.
Green light in biology : Green light has a significant impact on biological systems, people, animals and plants too. The photoreceptors respond positively (to green light rays) and initiate important processes inside the organism. Chlorophyll in the plant leaves contains green pigments, which reflect green light rays.
Green light is reflected by pigments in plants or or molecules of a green colored object. The other colors present in the light incident on the object or leaves are all absorbed. So red, blue, yellow etc. are absorbed and used for making photosynthesis. Means only light waves in the range of 510nm - 560nm (green light) are reflected. Then the leaves or a green object appears to be green, as green light falls in our eyes.
