#A0522DSienna is a dark, moderately saturated take on orange. Colors in this range are commonly associated with enthusiasm, friendliness and affordability, which makes sienna a natural fit for playful brands, food products and secondary calls to action.
With a 5.62:1 contrast ratio against white, sienna is dark enough to carry white text at any size — use it confidently for buttons, headers and filled UI elements. Against black text it manages 3.74:1, so stick with white type on sienna surfaces.
For pairings, the complement of sienna sits at 199° — #2D7B9F, close to steelblue — and delivers the strongest possible hue contrast; use it sparingly, in roughly a 90/10 split, so the two don't fight. For calmer schemes, the analogous colors 30° to either side keep the same warm temperature, while the triadic pair gives you a balanced three-color palette. All of these are computed for sienna in the palettes below, with copy-ready codes.
Every palette below is computed from sienna's position on the color wheel (hue 19°). Hover any swatch to see its code; click to copy.
Tints mix sienna toward white; shades mix it toward black. Use the scale for hover states, borders and depth without leaving the hue.
WCAG 2.1 requires 4.5:1 for normal text (AA) and 3:1 for large text. Here's how sienna performs, plus how it appears under the three main types of dichromatic color blindness (simulated approximation).
| Pairing | Ratio | Normal text | Large text |
|---|---|---|---|
| White text on Sienna | 5.62:1 | AA | AAA |
| Black text on Sienna | 3.74:1 | Fail | AA |
