Nature can be great for fun bright colors.

Fruits, vegetables and nature I find the easiest subjects in creating unique style patterns with colors that pop or more suttle. If you have a hard time pairing colors go out side go on nature walk to help create your choice of colors finding the main shades that come out at you. A leaf on tree behind the fruit can be your choices. Nature is the best guide for colors. Butterfly on a flower, ocean next to sky, or trees with birds can help you find great color combinations.

Is one example of pond with lotus, I did watercolor painting I pulled colors from it and creating the cranes colorway
