Kournikova is too light for white lettering and too active for long reading panels. Dark text, restrained areas, and clear spacing make the sunny yellow easier to control.
Banana Yellow makes a clear highlight within Kournikova’s sunny family. Periwinkle Blue offers a gentler court-line or stationery contrast than dark blue.
Across a large background, Kournikova feels sunny but controlled. In a small badge, it becomes much louder. Keep dark text on top; white disappears against this much light.
