#F3F9B1 sits at 65° on the color wheel, placing it in the yellow family of the warm half of the spectrum. With 86% saturation and 84% lightness, it reads as a fully saturated, very light tone — a soft but unmistakably tinted presence. Its RGB mix of 243, 249, 177 produces a 19.00:1 contrast ratio against black, which clears WCAG AAA for body text in that pairing.
In RGB space #F3F9B1 is a clear variant of CSS khaki — about 42 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 lift, air, and gentle emphasis. On screen the warm cast tends to pair best with cool neutrals around 210°-230° to balance temperature.
