New color displays

Here are the new color displays I have prepared, based on the suggestion of VMS Mosaic, for the colors red, yellow, green, and blue to resolve the ongoing dispute since May 2010 regarding which colors to use to represent the four psychological primary colors. I am following VMS Mosaic’s suggestion to blank out the color boxes and provide samples of the various colors in different color systems. This solution should satisfy everyone. This way, each person can decide for themselves which color they choose to regard as red, yellow, green, or blue.

Please leave your comments regarding this new primary colors display as I would like to install these new color displays within the next week. Keraunos (talk) 04:02, 6 October 2010 (UTC)

Various definitions of red

The definition of the color red depends on what color system is used to define the color red. The definition of red according to four of the major color systems is shown below.

Red (RGB) (X11 red)

The color defined as red in the RGB color system, i.e. X11 red, is shown at right. This tone of red is one of the three additive primary colors, along with green and blue. The three additive primaries in the RGB color system are the three colors of light chosen such as to provide the maximum gamut of colors that are capable of being represented on a computer or television set.

Red (CMYK) (Pigment red)

Cyan, magenta, and yellow are the three subtractive primary colors used in printing.

The color defined as red in the CMYK color system used in printing, also known as pigment red, is the tone of red that is achieved by mixing process (printer's) magenta and process (printer's) yellow in equal proportions. It is displayed at right.

The purpose of the CMYK color system is to provide the maximum possible gamut of color reproducible in printing.

The color indicated is only approximate as the colors of printing inks may vary.

The color defined as red in the NCS or Natural Color System is shown at right (NCS 1080-R). The Natural Color System is a color system based on the four unique hues or psychological primary colors red, yellow, green, and blue. The NCS is based on the opponent process theory of vision.

The “Natural Color System” is widely used in Scandinavia.

The hues of the Munsell color system, at varying values, and maximum chroma to stay in the sRGB gamut.

The color defined as red in the Munsell color system (Munsell 5R) is shown at right. The Munsell color system is a color space that specifies colors based on three color dimensions: hue, value (lightness), and chroma (color purity), spaced uniformly in three dimensions in the Munsell color solid according to the logarithmic scale which governs human perception.

The Munsell colors displayed are only approximate as they have been adjusted to fit into the sRGB gamut.

The color box at right shows the most intense yellow representable in 8-bit RGB color model; yellow is a secondary color in an additive RGB space.

The three additive primaries in the RGB color system are the three colors of light chosen such as to provide the maximum gamut of colors that are capable of being represented on a computer or television set.

The measured light spectrum from yellow pixels on a typical computer display is complex, and very unlike the reflectance spectrum of a yellow object such as a banana.^[2]

Process yellow (also known as pigment yellow or printer's yellow) is one of the three colors typically used as subtractive primary colors, along with magenta and cyan. The CMYK system for color printing is based on using four inks, one of which is a yellow color. The purpose of the CMYK color system is to provide the maximum possible gamut of colors capable of being reproduced in printing.

Process yellow is in itself a standard color, and a fairly narrow range of yellow inks or pigments are used. Process yellow is based on a colorant that reflects the preponderance of red and green light, and absorbs most blue light, as shown in the reflectance spectra shown in the figure on the lower right.

Because of the characteristics of paint pigments and use of different color wheels, painters traditionally regard the complement of yellow as the color indigo or blue-violet.

Process yellow is not an RGB color, and there is no fixed conversion from CMYK primaries to RGB. Different formulations are used for printer's ink, so there can be variations in the printed color that is pure yellow ink.
