Near-White Background
At 85% lightness, #EFFCB5 is very close to white but carries a subtle yellow tint. This is perfect for alternating row backgrounds in tables, subtle section differentiation, and adding warmth or coolness to an otherwise stark white design.
Attention & Optimism
#EFFCB5 is in the yellow spectrum (hue 71). Yellow attracts attention faster than any other color. Use it for warning labels, featured content markers, star ratings, and tooltip backgrounds. Pair with dark text since yellow often fails contrast checks against white.
