Four real design scenarios, with the recommended pick based on hue, saturation, and WCAG contrast.
Mustard Yellow is more saturated (99% HSL vs 89%) so it reads as bolder and more memorable at logo scale, while Dark Goldenrod can feel washed out when printed small.
Dark Goldenrod hits a 3.25:1 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.
Mustard Yellow is a warm tone that flatters spring/summer collections and warmer skin undertones, while Dark Goldenrod leans warmer and is better suited to autumn/winter layering.
Dark Goldenrod is the more muted of the two (89% saturation) and sits more calmly on large wall surfaces, while Mustard Yellow's higher chroma can overwhelm a room when used beyond accent pieces.
Dark Goldenrod (#B8860B) is a dark, vivid yellow with a warm undertone — it feels rich, serious, substantial and bright, energetic, eye-catching.
Mustard Yellow (#E1AD01) is a medium, vivid yellow 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.
