Macular pigment (MP) is a natural filter with ‘notch’ transmission characteristics. This chapter examines the effects of MP on surface colours in Normal and Anomalous Trichromats for a database of 1782 reflectance spectra. The results show that increases in MP concentration produce a general clockwise rotation of chromaticity around the illuminant point for Normals and Anormals. The chromaticity shifts, associated with rotation, increase with distance from the illuminant point.
