As the species name Hyla versicolor implies, Gray Tree Frogs are highly variable in color owing to their ability to camouflage themselves from gray to green, depending on the substrate they are sitting on. The degree of mottling varies. They can change from nearly black to nearly white. They change colors more slowly than a chameleon. Dead gray tree frogs and ones in unnatural surroundings are predominantly gray in color.
Gray tree frogs are primarily arboreal, spending time in wooded areas, usually not far from a permanent water source. On rainy evenings they can often be found calling in or near shallow, temporary pools of water, and often in swimming pools. They are nocturnal and insectivorous, consuming most any small arthropods they can catch. They will also eat algae if readily available.
