In the design phase I opted for a clean, dark mode interface to align with the sporty environment of the subject. To create contrast with the dark background and to highlight key elements, I used a green-y yellow or “grello” colour which is reminiscent of a tennis ball.

The top-down view of the the court was chosen to make the ball’s movement easy to track, creating a more engaging experience. Appropriate fonts were also selected to give the interface a sleek, modern feel, which complimented the high-energy nature of the design.
