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.
- Table from Field (1990); CIE data for Illuminant C from Poynton (2008).

Famous quotes containing the word colors:
“Nature always wears the colors of the spirit. To a man laboring under calamity, the heat of his own fire hath sadness in it.”
—Ralph Waldo Emerson (1803–1882)
“All our Concord waters have two colors at least; one when viewed at a distance, and another, more proper, close at hand.... Walden is blue at one time and green at another, even from the same point of view. Lying between the earth and the heavens, it partakes of the color of both.”
—Henry David Thoreau (1817–1862)
“Our frigate takes fire,
The other asks if we demand quarter?
If our colors are struck and the fighting done?
Now I laugh content for I hear the voice of my little captain,
We have not struck, he composedly cries, we have just begun our part of the fighting.”
—Walt Whitman (1819–1892)
