Intermezzo: A Visual Illusion Experiment – Part 11

ContrastIllusionPerspectiveIntermezzo, Public Domain

Continuing with the contrast illusion theme (see Appendix) I created the above picture to illustrate the theme.  Thus although all of the filled circles are of the same colour, this colour appears different in the context of the background. Quite accidentally there is a further illusion in the picture. The right side may appear wider than the left side. This is because the theme involves a depth perspective. The images on the left appear closer than those on the right and this interferes with the assessment of the width of the image.
