Colors
The colors of the chart were described by McCamy et al. with colorimetric measurements using the CIE 1931 2° standard observer and Illuminant C, and also in terms of the Munsell color system. Using measured spectral reflectance curves, it is possible to derive CIELAB values for Illuminants D65 and D50 and coordinates in sRGB.

Famous quotes containing the word colors:
“We may say that feelings have two kinds of intensity. One is the intensity of the feeling itself, by which loud sounds are distinguished from faint ones, luminous colors from dark ones, highly chromatic colors from almost neutral tints, etc. The other is the intensity of consciousness that lays hold of the feeling, which makes the ticking of a watch actually heard infinitely more vivid than a cannon shot remembered to have been heard a few minutes ago.”
—Charles Sanders Peirce (18391914)
“Color is my day-long obsession, joy and torment. To such an extent indeed that one day, finding myself at the deathbed of a woman who had been and still was very dear to me, I caught myself in the act of focusing on her temples and automatically analyzing the succession of appropriately graded colors which death was imposing on her motionless face.”
—Claude Monet (18401926)
“The light is there, and colors surround us. However, if there were no light nor colors in our own eye, we wouldnt perceive such things outside of us.”
—Johann Wolfgang Von Goethe (17491832)
