Coloring this big dump truck with different colors will make it look very attractive and real. When coloring the big dump truck try remembering the dump truck you see in the street and try to follow those colors. Like the wheels of the truck are always black so you should also try to keep them black. The windows are see through so a very light shade of blue or yellow can be used to make them look real. The front of the truck can be a shade of grey and the back where the dump is kept can be of different colors like yellow on the sides, the stripes can be given two three different colors. The bottom of the truck can also be yellow or other light colors. The background preferred should be of a light color so the dump truck looks prominent.
