Four watercolor traffic lights arranged horizontally on a stark white background, each showing a distinct signal state: vibrant translucent crimson red, warm muted ochre yellow, fresh spring-like green, and cool desaturated charcoal grey for the inactive light. Rendered in a loose, painterly watercolor style with soft color washes that bleed and blend, creating diffused effects and subtle internal glows within each bulb. The textured housings resemble weathered metal with visible brushstrokes and tonal variation. Delicate paper grain and gentle imperfections enhance the handmade, artistic illustration quality. Lighting is even and diffused, with no strong shadows or highlights, contributing to the calm, slightly nostalgic mood. Flat two-dimensional composition emphasizes simple forms and horizontal arrangement.
