Mustard

Mustard hits different from the other greens the moment it lands next to a label. This one is more sun-baked and earthy than Hot Sand, less metallic and punchy than Gold Tooth, and it doesn't have that warmed-brass softness of Old Gold. Mustard reads as a dry, dense yellow-olive rather than a clear gold or honey note.

I use it when I need "yellow" but still want it to behave like a green-family accent in layouts. Think CPG shelf labels, price callouts, and compliance-style tags where the color has to be noticeable without feeling like a metallic highlight. In ecommerce, it's great for promo pills on product grids, and it works for green-family interfaces where you want warmth to feel grounded, not bakery-bright.

Quirk: because it leans a little olive, Mustard can look flat beside very clean lime greens. If that happens, pair it with a slightly lighter sage or a warmer cream so the yellow doesn't get muted.
