Water Tanker Spraying a Dusty Road

A heavy water tanker rolls through a rocky work road, spraying a wide fan of water behind its rear bar.

🎨 How to color it

Color the tanker’s round tank steel blue, the cab construction yellow, the spray pale aqua, and the dusty hills tan with sage green trees. Use sharp pencils for the tire treads, ladder rungs, rivets, and grille, then switch to broader strokes for the tank and open sky. Try fading the wet road from dark brown near the spray to light beige where the dust is still dry.

Why Water Trucks Make Rainbows — By noon, the quarry road tasted like chalk, and Vesper had dust on both elbows. Read the full story →

By noon, the quarry road tasted like chalk, and Vesper had dust on both elbows. She wanted every driver to laugh before the lunch whistle, so she invented Puddle-Racers: whoever could make a tiny stream wiggle farthest around three pebbles won a pinecone crown. The trouble was, the ground drank every splash before the game could start. “Secret rule,” Vesper whispered to the water-truck driver, “we need a cloud with wheels.”

The driver opened the rear spray bar, and hissssss—water fanned across the ruts. Vesper chased the first silver trickle, steering it with her boot heel past a flat rock, a beetle tunnel, and the pinecone crown. Then the sun slipped from behind a cloud. Colors sprang up in the mist—red, gold, green, blue—so bright the whole crew stopped chewing their sandwiches.

Vesper cupped her dusty hands around the shine like it might hear her. “This race is for everybody,” she said. Ever since that noon in the quarry, water trucks have carried a little road-rainbow in their spray, just waiting for sun, dust, and someone with joy too big to keep secret.
