Sunflower Yellow
A high-saturation warm yellow that radiates energy

Sunflower Yellow is a high-saturation, warm tone that commands immediate attention. Because of its intense brightness, #ffda03 functions best as a strategic accent rather than a full page background. Pair it with deep charcoal or navy to ground the energy without losing readability. It offers excellent contrast for black text, making it a functional choice for buttons or call-to-action elements where visibility matters most.
