The short answer is: virtually any color you need. Powder coating is not limited to a handful of factory shades, so you can choose from standard colors, RAL classics, or fully custom matches for street benches.
Most manufacturers offer a standard color range that covers the shades you see most often in public spaces. These usually include anthracite grey, jet black, white or off-white, moss green, chocolate brown, cobalt blue, signal red, traffic yellow, silver, and beige or sand tones. If you want a quick reference, the most commonly ordered RAL colors for street benches are RAL 7016 anthracite grey, RAL 9005 jet black, RAL 6005 moss green, RAL 8017 chocolate brown, and RAL 5013 cobalt blue.
However, that standard palette is just the starting point. Because powder coating is applied as a dry pigment and cured in an oven, the powder can be formulated to match almost any RAL Classic or RAL Design color. Many suppliers also offer Pantone matching, corporate branding colors, or custom shades for wayfinding and public art projects. If you need a bench that matches a school logo, a park identity, or a streetscape palette, you can usually request a custom powder color with little or no extra cost, though lead time may increase slightly.
Color choice often depends on the setting. City streets and transit areas tend to use dark greys, graphite, or black because they hide scuffs and everyday grime. Parks and gardens often favor greens, browns, and earthy tones to blend with landscaping. Campuses, downtown districts, and branded spaces sometimes choose brighter colors like red, yellow, orange, blue, or even violet to create visual identity or improve visibility. Coastal areas may lean toward whites, light greys, and blues, while heritage or historic areas often go for bronze, dark green, or textured black.
Finish also changes how a color looks. Powder coating can be matte, satin, gloss, fine texture, or anti-graffiti. A textured anthracite grey will look very different from a smooth gloss black, even if they belong to the same color family. For outdoor street furniture, always ask for UV-stable polyester powder or a super-durable powder coat so reds, yellows, and blues resist fading and lighter colors resist chalking.
So, to answer directly: powder-coated street benches are available in standard black, grey, green, brown, white, silver, blue, red, and yellow, plus virtually any custom RAL, Pantone, or brand-matched shade. If you can describe the color you want, there is a very good chance it can be powder coated.
