An interesting preprint popped up on my physics eprints page this morning: “Fractal Dimensions in Perceptual Color Space: A Comparison Study Using Jackson Pollock’s Art.” by J. R. Mureika. Apparently, the standard RGB colour system used across the imaging industry from graphic design and photography to computer monitors and TV screens is not up to the job of representing fractal images and does not reveal the nuances of colour in perceptually different colours. Best avoid Pollock desktop wallpaper then!
