"Dissociation of stripes"
The eye in the upper-right image appears white while that in the lower-right one appears black, though they are the same black and white sinusoidal luminance grating as shown in the left image. It seems this illusion is based on amodal completion.

The eye in the upper-right image appears white while that in the lower-right one appears black, though they are the same black and white stripes as shown in the left image. It seems that this illusion is based on spatial color mixing rather than amodal completion.
Moreover, an eye made up of red, green and blue stripes (shown in the left image) can be an apparent white eye (shown in the upper-right image) or an apparent black eye (shown in the lower-right image). This illusion is based on spatial color mixing. In addition, the conventional wisdom that mixing RGB colors results in white is valid when all colors except the target are completely black.
"Illusory red with check patterns"
The Coca-Cola can appears reddish, though it consists of black and white check patterns.
