Why this tool is useful
Pure Cyan (#00FFFF) is a primary color in the CMY print color model and a crucial test for accurate color management between screen and print workflows. Designers working in print production use cyan screens to verify that their monitor cyan primary aligns with the ICC profile for their intended output device. If cyan looks too blue or too green, your monitor color profile needs recalibration using a hardware colorimeter.
