What Colors Go with Orange Brown? How to Create an Autumn-Inspired Color Palette

Orange brown combines the warmth of orange with the depth of brown. Because “orange brown” can cover a fairly broad range, this article uses orange brown ■#A0522D, the value of the CSS named color sienna, as a practical reference color for the web. If you want an autumn-inspired palette, a useful approach is to separate the roles of cream, olive, and deep blue-green instead of filling the entire design with warm colors.

Orange brown works best with pale surfaces and deep text colors

In HSL (Hue, Saturation, Lightness), a color model that describes color by hue, saturation, and lightness, orange brown ■#A0522D is approximately 19.3 degrees hue, 56.1% saturation, and 40.2% lightness. It is darker than a vivid orange, so it is often easier to control as an accent for headings, primary buttons, or badges than as a full-page background.

This reference color has a contrast ratio of about 5.62:1 with white ■#FFFFFF and about 3.74:1 with black ■#000000. Using the WCAG 2.2 (Web Content Accessibility Guidelines) minimum of 4.5:1 for normal text as a reference, white text is the more practical choice when this orange brown is used as a button background.

Three autumn-inspired color combinations

1. Cream and espresso brown for a warm, calm look

Use cream ■#FFF4E6 for the background, espresso brown ■#3B2A22 for body text and headings, and orange brown ■#A0522D for the main accent. The background and text have a contrast ratio of about 12.55:1. Even though the palette stays on the warm side, the large lightness difference between the surface and the text keeps the information easy to organize.

2. Oat beige and olive charcoal for a natural palette

Use oat beige ■#F3EFE3 for the background, olive charcoal ■#3F4A2F for body text and headings, and orange brown ■#A0522D for emphasis. The background and text have a contrast ratio of about 8.18:1. A yellow-leaning beige and a muted green can create a restrained, autumn-oriented palette without introducing too many competing colors.

3. Pale blue-gray and dark teal to make orange brown stand out

Use pale blue-gray ■#EEF3F3 for the background, dark teal ■#2F4F4F for body text and headings, and orange brown ■#A0522D for the accent. The background and text have a contrast ratio of about 7.97:1. Adding a small amount of a cooler blue-green creates more hue separation from the warm orange brown, which can make the main accent easier to locate.

Adjust the autumn feel with area and lightness, not just more colors

If orange, red, yellow, and brown are all used at similar strength, the design can lose a clear focal point. Once orange brown ■#A0522D is chosen as the main accent, keep backgrounds pale, body text deep, and nearby warm hues limited to decoration or smaller areas.

If you also want orange on a larger surface, use a tint or a lower-saturation yellow-orange for the background instead of covering the page with the reference color itself. Keep the stronger orange brown for buttons and headings. When photographs already contain many warm colors such as reddish brown or yellow leaves, shifting text and open space toward neutrals or blue-green can also reduce competition between the photography and the interface.

HueRoll can show tints, shades, complementary and analogous colors, several harmony suggestions, and 60–30–10 palette candidates from a selected base color. After choosing orange brown, decide the roles of “background,” “text,” and “emphasis” before narrowing the suggestions. HueRoll compares the selected color only with white and black in its contrast section, so the contrast ratios between other color pairs in this article were calculated separately.
