This image is an omnichromatic variation of Yet Another Monna Lisa.
The colour components of the original image are swapped and inverted in all possible ways, resulting in 48 images to choose from.
Of these, 2 are shortlisted based solely on the perceived intensity of expression of Monna Lisa's face. This appears to be mostly dependent on the contrast between the pupil and the iris and the rest of the eye.
This image is then ultimatey favoured because it also provides a peculiar ginger hair impression.
The image is finally passed through a process that makes it omnichromatic, which doesn't alter it much, because the original image is already quite colourful.
