This is a very broad question as there are a great many different species of tree frog. In most of the natural world, living things that change color do so for one of two reasons: breeding or defense. In the case of tree frogs the primary reason is most likely defense - by changing color they can either blend into the environment or repel predators.
no they are bright colors
Tree frogs are green and red. i like frogs. :)
no. they are not venomous. The bright colors they have are used as camouflage.
It depends on the type(s) of frog(s) you are talking about. Most frogs are green although some are other colors.
Frogs can come in a variety of colors including green, brown, red, blue, yellow, and more. Their coloration can also change depending on the species, environment, and individual genetics.
Their colors show emotions. If they are offended, they turn bright red. If they are annoyed, they turn black and grey. When they are green, they are calm.

any colors
No. No frogs are green. Frogs have no green pigmentation in their skin at all. Like mammals, they are unable to produce green pigment. Mammals, reptiles and amphibians can only produce black and yellow-red pigment, and all colours and patterns on a frog's skin are the result of different combinations of these two pigments. Frogs contain variations of the yellow-red pigment. Most species of frogs appear green because of the pattern of refraction of blue light by special cells in their skin blending in with this yellow pigment. To answer the question - green frogs are not completely green when they developing. The green colouring becomes more pronounced as they grow.
To turn green into black, you would have to mix it with a dark shade of red, such as maroon or burgundy, in order to neutralize the green color. Mixing these complementary colors will create a darker shade that will eventually turn black.
An anole can turn green, gray, black, and brown.
The color of the frogs dorsal side is not consistent. This is because many different frogs are many different colors.
