Plants grow best under a combination of red(620-750 nm) and blue(450-475nm)light and respond best to particular wavelengths within the light spectrum(given in nano-meters(nm). The wavelength that the plant will respond to best depends on what kind of plant it is and at what growth stage it is in. Generally the correct ratio of red to blue light will produce a magenta color. The most common way of producing this color in a light suitable for growing is LED. Compared to older generation grow lights they are much more expensive, however are much cheaper to run,have a longer life, and produces less heat.

How well would a plant grow under a yellow light?

Most plant life needs full spectrum lighting. In early stages of a flowering plant, it would need a blue and green spectrum (achieved with usually metal halide light) and then switched over to a red and orange spectrum (using high pressure sodium lighting). Growing a plant under pure yellow light will most likely make the plant grow quickly, but wiry - the stem will get really long and the top of the plant will most likely fall over eventually). It depends on the plant. Pure yellow light uses the red/orange spectrum and cacti do well in this type of lighting. Houseplants (which prefer blue/green spectrum) would most likely do poorly in "pure yellow light".
