Colour Measurement
Colour Measurement is a scholarly work, published in 1942 in ''Nature''. The main subjects of the publication include mathematics, optics, computer science, color constancy, artificial intelligence, observer effect, colorimetry, and statistics. PERRY'S letter on colour measurement1 may lead to misconceptions of the nature and status of the C.I.E. colorimetric system by colour workers who have not paid particular attention to the principles of colour measurement.
