Yes. In fact, our eyes are able to percieve colour when it receives the light reflected from the object. The rods in eyes convert the light waves into an impulse which gets transmitted to the brain and analysed. Then we are able to 'see' the colour.
Under a red spotlight, his jacket will not show up because it is red. His white shirt will appear red and his green trousers will appear black. This is because The red jacket is the same color as the light. His white shirt will turn red, since white reflects all colors, and since red is the only color, the white shirt reflects that color. His green trousers will appear black because there is no green that reflects off his trousers.
...reflected off of it. For example, leaves appear green as their pigment (chlorophyll) only reflects the wavelength of green light.
Black, obviously. The reason green leaves appear green is because when placed in white light, the leaf absorbs all the colors of the spectrum and reflects only green light. However, in red light, the leaf absorbs the red light but is unable to reflect any green light because there is no green to reflect. So, it appears black. Try watching green plants at night (or very low light conditions). That should give you a practical proof of the fact mentioned above.
because it reflects green light and absorbs the other visible wavelengths
The surface will look Red, because white reflects all colours and absorb none. If you hit a red light on, say, green then that would look black because green will absorb all the red but if it was a green light then it would look green. Every colour, except white, absorbs colours except itselves.
because it contains a green pigment called chlorophyll
because of chlorophyll
it reflects green light
The object will appear green because it absorbs all colors except for green, which it reflects back to our eyes.
An object that reflects green and red light would be some shade of yellow or orange, depending on the proportions.
Most plants appear green because they contain a pigment called chlorophyll, which absorbs sunlight for photosynthesis. Chlorophyll reflects green light, giving plants their green color.
presence of Chlorophyll in the cells of leaf reflects the green spectrum of light hence the leaf appear green.
The color of an object has to do with the waves of (visible) light that it reflects. When light hits an object some is absorbed and some reflects, e.g. white is white because all the colours are reflected back; black is black because none of the colours are reflected, red is red because only red reflects from the object. Plants are green because the chlorophyll reflects the colour green, making them appear green to us.

Leaves appear green because of a pigment called chlorophyll. Chlorophyll absorbs sunlight and uses it to make food for the plant through a process called photosynthesis. This pigment reflects green light, giving leaves their green color.
Its frequency (wavelength).
Because plant cells have organelles called Chloroplasts, which all contain Chlorophyll. It is a crucial part in photosynthesis that a certain frequency of light reaches this chlorophyll - this frequency range does not include Green frequency - so green light is reflected instead of absorbed, ergo plants appear to be green.
