Why this tool is useful
Green Yellow (#ADFF2F) is a vivid yellow-green that occupies the high-luminance peak of human color vision sensitivity. Because our eyes are most sensitive to wavelengths near this hue, even small inaccuracies in your display yellow-green rendering are immediately perceptible. Mapping software developers, sports broadcast engineers, and military visualization teams use this hue to verify that alert and highlight colors will render at maximum perceptual impact.
