Bermuda grass does best in regions of the country where there is lots of sun. For instance, it will do better in the State of Florida versus cloudier Seattle, Washington. Bermuda grass is naturally reseeding and can tolerate high heat and humidity. Basically you just need to water as needed, use a lawn fertilizer that is specifically for Bermuda grass in the spring and expect for the grass to turn brown in the winter months. That is really the only drawback to this type of grass. I guess I could have simplified my answer just by saying fertilize in spring and water the grass as needed :-). I have centipede grass currently and live in the southern climes and have been tempted to switch to Bermuda grass just for the simple fact that it is easier to care for.

If a black sheet of plastic is laid on the grass, the grass will turn yellow because the the starch produced in the grass gets consumed up . since no sunlight is available to the plant to produce more starch,it will gradually start turning yellow. ;-) ---------------------- The loss of green coloration equals the loss of chlorophylls, which is the result of the plant putting chlorophylls in storage when sun light is absent.
