Why this tool is useful
Crimson Red is a bold fully saturated red positioned at the edge of the sRGB color gamut. Use this screen to check red channel clipping: if the color appears the same brightness as a slightly lighter red, your display is clipping the red channel and losing highlight detail in red objects. Sports photography, especially motorsport and sporting event coverage, depends on accurate saturated red rendering for team livery and uniform colors.
