This wonderful cartoon scene featuring two singing rabbits is sure to spark some imagination! The light brown rabbit stands out against the dark brown one, both open-mouthed and lifting their arms in joy. To bring the picture alive, start by coloring a warm brown on the dark rabbit's fur, and lighter one on the other. Bring out the details of their faces with a slightly darker shade and draw attention to their fluffy fur with streaks of darker and lighter tones. Bring out the eyes of the light rabbit with a touch of yellow, and add some blue or purples around the ears to provide even more contrast. Add some warmth to the background with a light yellow-orange, or combine blues and greens for a cool, calming atmosphere.
