Munker-White illusion
White’s illusion demonstrated with achromatic colours.
An illusion which uses bands of colour, where the lightness/value of a colour is shifted, due to the surrounding context. Note that this illusion appears similar to simultaneous contrast, but it is not the same effect.
Example (achromatic): White’s illusion uses grey areas interspersed within black and white stripes. The perceived lightness/value of the grey shifts, depending on the surrounding areas.
Example (chromatic): The Munker-White illusion on the left uses coloured areas interspersed within black and white stripes. Note how neighbouring colours influence each other. The Munker-White illusion on the right uses various colours in juxtaposed areas. Coloured stripes may produce shifts in any of the colour attributes.
