Ishihara Colour Vision Deficiency Test

The CHBH MEG Lab has the 14-plate Ishihara Test for Colour Deficiency "Colour Blindness".

The current passing score is 12 correct of the 14 red/green test plates (not including the demonstration plate) indicating normal colour vision.
Any score below 12 indicates colour vision deficiency.

Unfortunately the type of red-green deficiency ("protan" or "deutan") in Participants cannot be characterised as those test plates are not available in the book.
