The dorsal blend in with the water, and the ventral blends in with the bottom surface. So they can tell if its dangerous if it is brightly colored. ( bright red frog= poisonous and non-tasty frog) :D - < I'm not sure if this right...I just guess..>
P.S.
This is exactly the same question on my science worksheet!
Frogs usually have a dark green or brown dorsal color and a white or yellowish ventral color. This helps them blend in with the water surface from above and the water surface from below as well giving protection from underwater and above water predators.
Yes!
The dorsal side has a more dark color so that it is able to blend in with moss or lily pads in the water. Where as the ventral side is a more yellow color so it blend with plants underneath the water and out of preys sight.
It helps them camouflage itself from predators. Although the answer above is true, here is a more informative answer. The bottom of the frog is a lighter color then the top. This is because if the frog is floating on top of the water, and prey or a predator looks up and the frog, the suns glare makes the frog harder to see. Also, there are darker splotches on the bottom so it doesn't show the silhouette for the frog. the top of the frog is darker because when swimming at the bottom of a murky lake, it blends in with the bottom.
A frog is a tailless amphibian, having a short squat body and very long hind legs for leaping. The color of the dorsal surface is green while the ventral surface is off-white.
There is frequently different coloration between the ventral and dorsal surfaces of many parts of the body. Coloration differences may be due to the different degree of sunlight protection that the two surfaces require. The dorsal surface is normally exposed to more sunlight... and damaging rays. It may also be a sort of communication tool as well, since exact posture and attitude is more visible with color or cast distinctions between the two surfaces.

greenAnother AnswerA green sea turtle is a dark green on the dorsal side (back) and a light cream or white color on the ventral side (bottom).
leeches are generally olive green at dorsal surface. orange yellow and orange at ventral surface. Distinct strips of orange, yellow and orange black color present on both sides. A median black strip is lying on dorsal side.
The dorsal stripe is made of normal hair coat, just a different color.
The color of the frogs dorsal side is not consistent. This is because many different frogs are many different colors.
The thalamus is black. The thalamus is in the dorsal portion of the substantia nigra which contains dopamine and malanin, making the color black.
