Monochrome Controls the color saturation of all linework while maintaining
the luminance. When turned on, the linework appears in varying shades of
gray starting at black if the background color luminance is 50 percent or more.
If the background color luminance is less than 50 percent, then the colors are
inverted, with the darkest linework displaying in white, and the lightest
linework displaying in black.
