For the coloring page, I suggest coloring the Kit a cool brown and white. highlight its tail and its long body with shades of warm brown and white, so that we can see the contrast of the colors. The Kits webbed feet can be colored a deep blue or dark green, with small highlights of white to show how the fur glistens in the water. The fish and frog, and insects can be brightly colored like yellow, green, red, blue and purple, to add an extra bit of dimension and brightness to the page. To finish, use white to bring out the details of the Kits fur and head, and add some wispy streaks of white and brown to the water, to create a lovely underwater effect.
