Why this tool is useful
Light Slate Gray (#778899) is a cool blue-tinted medium gray that tests your monitor gray-color temperature in the mid-range. Many displays render neutral grays with a slight warm or cool cast that only becomes apparent when compared against a known reference gray. If light slate gray appears obviously blue-tinted or warm-neutral, your monitor white point is set incorrectly and all neutral tones in your work will carry that systematic error.
