==Colorimetry==
Ives was also an important contributor to the development of the science of colorimetry. His paper of 1915 <ref>Ives, F. E. (1915) 'The Transformation of Colour-Mixture Equations from One System to Another', in MacAdam, D. L. (ed.) Selected Papers on Colorimetry -Fundamentals. 1, 1993 edn. Bellingham, Wash., USA: SPIE Optical Engineering Press</ref> proposed a color model in the form of a cube, with three of the vertices forming a triangle for the [[additive color|additive]] primaries, three others a triangle for their secondary colors, and the two remaining (opposite) vertices for black and white. A similar model was adopted by the [[International Commission on Illumination]] (CIE) as the basis of their [[CIE 1931 color space|color space]] drawn up in 1926, revised in 1931, which has been influential on all scientific color studies since then.<ref>Malacara, D.
