The main difference between Mustard Yellow and Greige is hue — Mustard Yellow is a warm yellow, while Greige is a warm orange. Mustard Yellow (#E1AD01) has an HSL of 46°, 99%, 44%, whereas Greige (#B2A591) sits at 36°, 18%, 63%.
Four real design scenarios, with the recommended pick based on hue, saturation, and WCAG contrast.
Mustard Yellow is more saturated (99% HSL vs 18%) so it reads as bolder and more memorable at logo scale, while Greige can feel washed out when printed small.
Greige hits a 2.42:1 WCAG contrast against white — safer for text-heavy interfaces — where Mustard Yellow only reaches 2.06:1 and risks failing AA at small body sizes.
Greige is a warm tone that flatters spring/summer collections and warmer skin undertones, while Mustard Yellow leans warmer and is better suited to autumn/winter layering.
Greige is the more muted of the two (18% saturation) and sits more calmly on large wall surfaces, while Mustard Yellow's higher chroma can overwhelm a room when used beyond accent pieces.
Mustard Yellow (#E1AD01) is a medium, vivid yellow with a warm undertone — it feels balanced, versatile and bright, energetic, eye-catching.
Greige (#B2A591) is a light, muted orange with a warm undertone — it feels airy, soft, approachable and subdued, sophisticated.
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.
