The rat in this coloring page is a marvel of detail, with its long tail and front paws outstretched. Its large ears, beady eyes, and brown fur give the rat a realistic look. The picture is framed by a white belly that creates an interesting contrast. To make this picture unique, try using two complimentary colors to shade the rat – a bright blue and a soft pink to really draw attention to the animal and highlight its features. Use the gold coin as a chance to play around with contrast and shading, perhaps veering away from realistic colors and opting for something brighter. Finally, the white fur and backdrop can be highlighted with a shade of yellow to make it really stand out. This coloring page can be easily customized to reflect the artist's personality and style.
