Only 26 units of blue enter #F5C71A; red reaches 245 and green 199. The imbalance explains its concentrated, warm-yellow center.

Indigo makes the cleanest opposing field. Racing green gives it a sporting tone, and raspberry turns the pairing playful. Graphite works when the lemon mark should carry all the color.

This is a useful yellow when a tiny element must survive a busy page. Think score markers, numbered tabs, route changes, or a short annotation beside a dark diagram.
