Advanced Investigation of Binocular Colour Vision

Review the Viewing Method if required.

'Filling-In Illusion'.  This is a tentative explanation for how the colours come to fuse in the other examples.  No image fusion is required.
    The illusion works best when there is no boundary between the differently coloured areas.

Counter Examples to the idea that the Filling-In Illusion is responsible for the Bicovi effect are presented.  The examples show that the Bicovi colour fusing works best with a boundary, contrary to the Filling-In Illusion.
    If the central boundary is simply removed, the darker colours will be obvious and fusion will not occur to give a match for the surrounding reference colour.  (See also the "Whiter" section.)
    However, colour matching can be achieved by equalizing the Values of the central and surround colours.  This is reflected in the "Value Corrected" links.
