Theinfobox with the name{{Infobox color}} is a table found on Wikipedia articles setting out information about a named color – an example can be found on the right.

The pieces of the infobox include:

1. At the top of the infobox is thecommon name of the color.
2. Below is an optionalpicture representing the color. For example, a collection of red objects.
3. An optionalrange of frequencies and wavelengths representing aspectral color. These are only approximations as different sources will have different ranges, and people will perceive the boundaries to be at different points.
4. Optionallyset(s) of color coordinates, referring to a specific color.^{[note 1]} Each color coordinate gives the specific color in onecolor 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 theRGB color spaces as commonly used by computers and video displays. NormallysRGB is used.
   CMYK color model: The coordinates in CMYK space as commonly used during colorprinting. Colors represented by CMYK coordinates vary greatly between printers depending on the inks used.
   HSV color space: The HSV space is atransformation from RGB space. As a transformation of RGB values, HSV values share the same limitation.
   Source: The source of the standard defining the color coordinates.
5. Examples ofother variations ("shades") of that color.

It must be noted that a range of color-variations is commonly associated with every color-name – however, only one specific variation is shown in detail: E.g. in the example only one tone of red (#FF0000) is shown in detail, while several variations of red can be found at the end of the infobox.
