The main difference between Sienna and Ochre is brightness and saturation: both are orange shades, but Ochre is lighter and Ochre is more saturated. Sienna (#A0522D) has an HSL of 19°, 56%, 40%, whereas Ochre (#CC7722) sits at 30°, 71%, 47%.
Four real design scenarios, with the recommended pick based on hue, saturation, and WCAG contrast.
Ochre is more saturated (71% HSL vs 56%) so it reads as bolder and more memorable at logo scale, while Sienna can feel washed out when printed small.
Sienna hits a 5.62:1 WCAG contrast against white — safer for text-heavy interfaces — where Ochre only reaches 3.37:1 and risks failing AA at small body sizes.
Ochre is a warm tone that flatters spring/summer collections and warmer skin undertones, while Sienna leans warmer and is better suited to autumn/winter layering.
Sienna is the more muted of the two (56% saturation) and sits more calmly on large wall surfaces, while Ochre's higher chroma can overwhelm a room when used beyond accent pieces.
Sienna (#A0522D) is a medium, moderately saturated orange with a warm undertone — it feels balanced, versatile and balanced in intensity.
Ochre (#CC7722) is a medium, vivid orange with a warm undertone — it feels balanced, versatile and bright, energetic, eye-catching.
Text legibility depends on the contrast ratio between foreground and background. WCAG 2.1 AA requires at least 4.5:1 for normal text and 3:1 for large text; AAA requires 7:1. Use these numbers to choose accessible combinations for your design.
