This scale factor varies not only from observer to observer—as will be evident from the existence of colorweak as well as color-blind observers—but from point to point on the retina of the same observer, as shown by the change in apparent hue in passing from the fovea to the periphery of the retina.

  8. The standard symbol of the Illuminating Engineering Society for "reflection factor" is ρ. On that basis the quotients would be respectively ρx, ρy, and ρz; their differences ρx—ρyz—ρy;their ratios ρx/ ρyz/ ρy. X ≡ ∫Φλρλdλ/ ∫Φλdλ, XcρX ≡ ∫Φλρλdλ/ ∫Φλdλ,Y ≡ ∫Φλρλdλ/ ∫Φλdλ ≡ Yc ≡ ρY,Z ≡ ∫Φλρλdλ/ ∫Φλdλ, Zc ≡ ρZ ≡ ∫Φλρλdλ/ ∫Φλdλ. Xc, Yc and Zc are the mean ordinates obtained from spectrophotometric curves for reflection samples by the method of selected ordinates.
  9. It will be evident that this will be true for any other standard illuminant, and that any nearly neutral color will have nearly the same coordinates under various nearwhite illuminants (color-constancy).
