Why this tool is useful
Pure Green (#00FF00) at full intensity is the display green primary color and is essential for verifying green channel performance in isolation. Beyond hardware testing, this color is also used as a virtual green screen background for photographers and videographers testing their keying software without physical chromakey fabric. Check that pure green appears fully saturated without any shift toward yellow-green or blue-green, which would indicate phosphor or LED degradation.
