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)

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.
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.
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 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.
