Why this tool is useful
Pure Yellow (#FFFF00) is the display secondary yellow color produced by combining the red and green channels at maximum intensity. Testing with pure yellow reveals any imbalance between the red and green primary channels. If yellow appears orange-tinted, the red channel is dominant; if it appears green-tinted, the green channel is stronger. Automotive photographers, sports content creators, and caution-symbol designers depend on accurate pure yellow rendering.
