#FFA500

CSS color

Overview

Orange bridges red and yellow on the warm side of the spectrum, defined in CSS as rgb(255, 165, 0), hex #FFA500. Its full red channel and partial green place it at 38 degrees on the hue wheel at complete saturation and brightness. Part of the extended CSS3 named colors rather than the original sixteen, orange is a spectral color near 600 nanometers and one of the few hues named after an object โ€” the fruit โ€” rather than the reverse. Warm, high-energy, and highly visible, it reads clearly at small sizes and is a common signal and accent color, complementing the blues that sit opposite it on the wheel.

Orange (#FFA500) is the pure CSS orange โ€” a vivid, warm hue occupying the spectrum between red and yellow, named directly after the orange fruit introduced to Europe in the 15th century from Asia. As a CSS named color, it delivers maximum orange energy and is associated worldwide with optimism, enthusiasm, harvest, and affordable value. It's one of the most psychologically stimulating colors in the visible spectrum.

Properties

Color Psychology

True orange embodies enthusiasm, creativity, and adventure. It stimulates mental activity and social interaction, making it a favorite in creative industries. Orange is highly visible and conveys confidence without the aggression of red, bridging warmth and energy.

Design Usage

Medium orange excels in CTAs, pricing highlights, and gamification elements where excitement is desired. Tech companies and SaaS products use it to differentiate from the dominant blue of their competitors. It requires careful contrast checking since mid-range orange can fail WCAG on light backgrounds.
