Cie xyy

- Instead, the
**CIE**1931 xy coordinate system is used. Unlike color temperature,**CIE**1931 xy coordinates are two-dimensional , and a specific color can be pinpointed using a pair of coordinate values. Every color temperature can be plotted on the**CIE**1931 xy coordinate plane and expressed as a pair of xy coordinates rather than a Kelvin value. - The
**xyY**space is a cross between the**CIE**XYZ and its normalized chromaticity coordinates xyz, such that the luminance Y is preserved and augmented with just the required two chromaticity dimensions. See also.**CIE xyY**(chromaticity diagram) Chrominance; rg chromaticity; Impossible color; Color index in ... - For more details see The
**CIE**XYZ and**xyY**Color Spaces, and Bruce Lindbloom's**xyY**to XYZ, and XYZ to**xyY**. The outer edge of the horseshoe-shape corresponds to various spectrally pure wavelengths of actual light that humans can see, which is why I said XYZ and**xyY**are connected by "surprisingly" simple equations: it surprises me that XYZ values ... - The
**CIE**1931 color spaces were the first defined quantitative links between distributions of wavelengths in the electromagnetic visible spectrum, and physiologically perceived colors in human color vision. ... The derived color space specified by x, y, and Y is known as the**CIE xyY**color space and is widely used to specify colors in practice.
