Why this tool is useful
Crimson (#DC143C) is a deep saturated red with blue undertones that makes it distinct from pure red. Testing your display with crimson reveals whether your red channel bleeds into the blue channel at high saturation, a common fault in older LCD panels. Fashion brands in the luxury and evening-wear space rely on accurate crimson rendering because it is a signature color in premium red garments and packaging.
