As you look closer at the scene, you will find a friendly mermaid cat as the center of attention. Nearby, a small school of fish swims along, following the trail of tiny bubbles rising to the surface. The ocean floor is decorated with textured coral and flowing seaweed that sways with the current.

Don't forget to spot the cheerful starfish resting on the seabed and the delicate shells scattered among the rocks. Every part of this image, from the cat's whiskers to the patterns on the fish, offers a chance to use different colors.

Since this is a fantasy creature, you can choose any colors you like for the mermaid cat's fur and tail. Try using bright, metallic shades for the scales to make them look like they are reflecting sunlight under the water. For the coral and seaweed, using a mix of warm oranges and cool greens creates a nice contrast against the blue water.

You can use light blue or soft teal for the background water to help the fish and bubbles stand out. Colored pencils are great for blending different shades on the cat's tail, while markers can make the tropical fish look extra vibrant.
