Why this tool is useful
Pure Magenta (#FF00FF) is one of the three primary colors in the CMY color model and an essential test for your display red-blue channel combination accuracy. It tests whether your monitor red and blue primary channels are perfectly balanced. If magenta appears pink, red is dominant; if it appears purple, blue is dominant. Graphic designers working across print and digital workflows use magenta screens as a cross-media calibration reference point.
