Orange or Blue: Which to Use and Where

Four real design scenarios, with the recommended pick based on hue, saturation, and WCAG contrast.

▢Web UI & body text backgrounds
PickBlue

Blue hits a 8.59:1 WCAG contrast against white — safer for text-heavy interfaces — where Orange only reaches 2.33:1 and risks failing AA at small body sizes.

⬡Fashion & apparel
PickOrange

Orange is a warm tone that flatters spring/summer collections and warmer skin undertones, while Blue leans cooler and is better suited to autumn/winter layering.

Orange is the more muted of the two (100% saturation) and sits more calmly on large wall surfaces, while Blue's higher chroma can overwhelm a room when used beyond accent pieces.
