In the center of the page, a happy plumber wears a classic baseball cap and comfortable overalls over his shirt. He is holding a large wrench and focusing on the faucet above the countertop. A single, round water drop is caught mid-air, showing exactly where the leak is happening.

Behind him, you can see the simple outline of a mirror and the pipes tucked neatly under the sink. Every part of the bathroom, from the smooth surface of the counter to the metallic shine of the plumbing fixtures, is waiting for some color. The plumber's friendly expression makes this repair look like a fun puzzle to solve.

For the plumber’s outfit, try using bright blue or red for the overalls to make them stand out. You can use a soft grey or even a light blue for the faucet and wrench to give them a metallic look. To make the water drop look realistic, a tiny bit of light blue or turquoise works perfectly.

Since this is a bathroom scene, the countertop could be a neutral tan or marble-like grey. If you want to add some shine to the mirror, leave a few small areas white or use a very pale blue. Don't be afraid to use bold colors for the plumber's shirt and cap to show off his personality while he works.
