Sensible jobs for this swatch

subtle surfaces, chips, and table stripes

Family context: Optimism, attention, and warmth. Ideal for highlights, warnings, and cheerful brands. Common uses still include buttons, charts, and accents in the Yellow range — always verify the pair for this exact hex in the contrast checker.
