Middle-grey sRGB values (with „middle“ defined as „emitting half as much visible light per area as a maximum brightness white“ and „grey“ defined as „having the same chromacity as the standard illuminant D65“) are near 188,188,188, assuming the γ correction formula from the sRGB standard is in use.
It is an iterative algorithm which works in two stages. The first stage is to use the red, green and blue color space with the intensity normalized, to normalize each pixel. The second stage is to normalize each color channel separately, so that the sum of the color components is equal to one third of the number of pixels.
On the other hand, some color spaces such as RGB and XYZ do not separate out chromaticity, but chromaticity is defined by a mapping that normalizes out intensity, and its coordinates, such as r and g or x and y, can be calculated through the division operation, such as x = X / X + Y + Z , and so on.
Hexadecimal 8-bit RGB representations of the main 125 colors. A color in the RGB color model is described by indicating how much of each of the red, green, and blue is included. The color is expressed as an RGB triplet (r,g,b), each component of which can vary from zero to a defined maximum value. If all the components are at zero the result is ...
[note 1] Each color coordinate gives the specific color in one color space (e.g. RGB), and one standard (e.g. sRGB). [note 2] The following color spaces can be found in a color infobox: Hex triplet: RGB values as a 24-bit hexadecimal value. RGB: The coordinates in one of the RGB color spaces as commonly
The test chart shows the full 256 levels of the red, green, and blue (RGB) primary colors and cyan, magenta, and yellow complementary colors, along with a full 256-level grayscale. Gradients of RGB intermediate colors (orange, lime green, sea green, sky blue, violet, and fuchsia), and a full hue spectrum are also present.

Aqua (Latin for "water") is a variation of the color cyan.The normalized color coordinates for the two web colors named aqua and cyan are identical. It was one of the three secondary colors of the RGB color model used on computer and television displays.
