There is actually more than one type of chlorophyll, and they reflect and absorb different colors (one is blue-green, one just green, and one yellow-green). Land plants make heavy use of blue and red light, and algae that live in the ocean use more blue.
The main color reflected by chlorophyll is green (thus the color we actually see). In the fall, when leaves change color then we start to see some of the other colors reflected albeit in much lesser intensities (yellow, brown, red). Chlorophyll actually absorbs all wavelengths of color (including a small amount of green) and contains compounds that use those wavelengths for chemical reactions such a beta carotene using the orange wavelength.
