About Invert image colours
Inverting replaces every colour with its opposite: each RGB value becomes 255 minus itself, so white turns black and blue turns yellow. The result looks like a photographic negative. It is also handy for turning scanned film negatives positive or flipping a black-on-white diagram for dark mode.
