Sienna (#882D17) is a warm, earthy hue that captures the essence of natural clay and sunset glows. This rich reddish-brown color sits perfectly between red and brown on the color wheel, offering designers a sophisticated alternative to standard earth tones.

Named after the Italian city of Siena, this natural pigment has been prized since Renaissance times for creating realistic skin tones and adding depth to landscapes. In modern design, sienna conveys stability, warmth, and rustic charm—making it ideal for brands seeking to communicate reliability and natural authenticity.

Sienna works beautifully in autumn palettes and pairs exceptionally well with complementary colors. For balanced contrast, combine it with mint green or sky blue. To create harmonious earth-tone schemes, pair sienna with terracotta, burnt orange, or olive green. For elegant sophistication, try combining it with cream or sage.

In UX/UI design, sienna serves as an excellent accent color for call-to-action buttons and navigation elements, providing warmth without overwhelming users. Its natural, grounding qualities make it particularly effective for outdoor brands, artisanal products, and wellness-focused designs where trust and authenticity are paramount.
