The color defined as blue in the RGB color model, X11 blue, is shown at right. This color is the brightest possible blue that can be reproduced on a computer screen, and is the color named blue in X11. It is one of the three primary colors used on the RGB color space, along with red and green. 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.
This color is also called color wheel blue. It is at precisely 240 degrees on the HSV color wheel, also known as the RGB color wheel. Its complementary color is yellow.

The color defined as blue in the Munsell color system (Munsell 5B) 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 elongated oval at an angle shaped Munsell color solid according to the logarithmic scale which governs human perception. In order for all the colors to be spaced uniformly, it was found necessary to use a color wheel with five primary colors--red, yellow, green, blue, and purple.
The Munsell colors displayed are only approximate as they have been adjusted to fit into the sRGB gamut.
