This project's design leverages a focused colour palette for clear purpose: primary blue (HSL 201, 76%, 46%) and lighter blue (HSL 200, 79%, 67%) define backgrounds and shapes, providing a stable foundation. A vibrant yellow (HSL 47, 100%, 60%) highlights all action buttons and CTAs for immediate user attention, while a dark grey (HSL 210, 7%, 21%) ensures readability for all text. White (HSL 0, 0%, 100%) provides essential contrast and clean design space.
