False Color

False color is an exposure-monitoring tool that replaces the image with a palette where each color represents a specific brightness range, from clipped highlights to crushed blacks. Instead of guessing, a cinematographer or colorist reads the picture by color: a common scheme shows skin as green or pink, overexposed clipping as red, and underexposed areas as blue or purple. On set it confirms faces are exposed correctly and that nothing important is blown out before rolling. In the grade, it helps verify whether highlights are recoverable or already clipped and where shadow detail still lives. Because it strips out hue and shows pure luminance zones, false color is far more precise than eyeballing exposure on an uncalibrated monitor, especially in tricky lighting.
