title: How metamer mismatching decreases as the number of colour mechanisms increases with implications for colour and lightness constancy.
abstract: Metamer mismatching has been previously found to impose serious limitations on colour constancy. The extent of metamer mismatching is shown here to be considerably smaller for trichromats than for dichromats, and maximal for monochromats. The implications for achromatic colour perception are discussed.
