Color gamut boundary optimization of wide gamut display devices
SPIE Proceedings, 2011High-end monitors based on LCD technology increasingly address wide color gamut implementations featuring precise color calibration within a variety of different color spaces such as extended sRGB or AdobeRGB. Combining a Look- Up-Table method with linear interpolation in RGB component space using 3x3 matrix multiplication provides optimized means ...

Preferred color gamut boundaries for wide‐gamut and multiprimary displays
Color Research & Application, 2012Preferred chroma enhancement and its dependence on hue are studied in a two‐part experiment using a wide‐gamut multiprimary display. Earlier research showed a clear dependence on hue but was limited by the gamut of the display it employed; the present work builds on this while easing the gamut constraints. In the first part of the present experiment, a

Color gamuts in dim illumination
SPIE Proceedings, 2008Rods act as color receptors in dim illumination. Several recent studies have measured the range of colors at low-light levels in different illuminants. This paper reviews these results and adds new experiments using long-wave-rich illumination, appropriate for rod and long-wave cone interactions.

Color Management for Wide-Color-Gamut UHDTV Production
SMPTE Motion Imaging Journal, 2015Ultrahigh-definition television (UHDTV) is a wide-color-gamut system, as standardized in Rec. ITU-R BT. 2020 and SMPTE ST 2036-1, that covers most real object colors and encompasses the gamuts of high-definition television (HDTV), Adobe RGB, and Digital Cinema Initiative Primary 3 (DCI-P3).

Three-dimensional color gamut for color-space-modulation
2016 22nd Asia-Pacific Conference on Communications (APCC), 2016In this paper, we consider color gamut multi-dimensionally for optimal constellation design in the color-space-based modulation methods. If points of some symbols are outside the three-dimensional color gamut, this can be a serious problem such as non-uniformity of the target color and the degradation of SER performance.

Generic device color gamut description
Color Research & Application, 2007AbstractThis article describes two methods for N‐dimensional device color gamut representation: one is for gamut surface description, the other for gamut volume description. Both methods combine analytical and geometrical approaches. These methods can be applied to any colorant spaces such as 3‐Dimensional RGB or CMY, 4‐Dimensional CMYK, 6‐Dimensional ...

Analysis of Color Gamut in Color 3D Printing
2020At present, color 3D printing technology has been applied in many fields, such as 3DP-based gypsum powder printing technology, plastic-based FDM printing technology, paper-based LOM printing technology, PolyJet printing technology and so on. All of these can realize mixed color 3D printing including gradient color.

21.4: Primary Design of Wide‐Color‐Gamut Displays for Matching the Color Gamut of Objects
SID Symposium Digest of Technical Papers, 2007Abstract The method for designing the primary color coordinates of the wide gamut display that its color gamut matches object color gamut the best is studied so that the display can reproduce object color the most vividly. The display with three monochromatic primaries is taken as an example.

Measurement of a Color Gamut Obtained from FD&C Colorants
Journal of Pharmaceutical Sciences, 1964A method is illustrated to determine what colors may be achieved utilizing the FD&C aluminum lakes as colorants. Lakes were mixed with a tablet excipient, compressed, and the reflectance was measured. A color solid was constructed at fixed values of lightness.
