#EFBF00 Hex Color
Glowing gold with real punch
Bright, glowing yellow with a golden edge. #efbf00 is loud by nature, so give it the accent role in a 60/30/10 palette instead of full backgrounds. It suits sale graphics, budget branding, and construction signage. Pair it with deep teal or charcoal, and use black text on it, which clears WCAG AA with room to spare.
