#F9E851 sits at 54° on the color wheel, placing it in the yellow family of the warm half of the spectrum. With 93% saturation and 65% lightness, it reads as a fully saturated, light tone — an immediate, signal-grade voice that demands attention. Its RGB mix of 249, 232, 81 produces a 16.69:1 contrast ratio against black, which clears WCAG AAA for body text in that pairing.
In RGB space #F9E851 is a clear variant of CSS khaki — about 60 units away from #F0E68C. Designers reach for yellow hues at this saturation when the brief calls for bold, immediate signal, and at this lightness when they want a present, comfortable mid-canvas voice. On screen the warm cast tends to pair best with cool neutrals around 210°-230° to balance temperature.
