NEC SpectraView 2190 - Color Space; Information Window - Color Gamut Tab

SPECTRAVIEW II - USER’S GUIDE | 25
Information window - Color Gamut tab
The Color Gamut tab graphically illustrates the color gamut of the display for comparison purposes as a 2D
representation of the 3D color gamut volume. The display’s color gamut can be compared to the color gamut
of several popular color spaces.
The source of the color measurements for the display’s color gamut will depend on the Primary Colors
Chromaticity Source setting in the Preferences dialog.
Selecting a reference color space will overlay the color gamut onto the display’s.
Colorspace
CIE xy - shows the gamut projected in CIE xy colorspace. This is probably more familiar to
most users, however it does not allow color differences to be easily judged because this projection
overemphasizes differences in green colors, and underemphasizes differences in blue colors.
CIE u’v’ - shows the gamut projected in CIE u’v’ colorspace. This is projection is an improvement
over CIE xy in that different colors are more equally represented in scale.
Show back body curve - shows the black body locus as yellow curve.
Show Target white point - shows the White Point of the currently selected target as a green X.
