Wikipedia:How to read a color infobox
This page is a how-to guide detailing a practice or process on the English Wikipedia.
|sRGBB (r, g, b)||(255, 0, 0)|
|CMYKH (c, m, y, k)||(0, 100, 100, 0)|
|HSV (h, s, v)||(0°, 100%, 100%)|
|B: Normalized to [0–255] (byte)
H: Normalized to [0–100] (hundred)
|Some shades of Red|
The pieces of the infobox include:
- At the top of the infobox is the common name of the color.
- Below is an optional picture of representing the color. For example a collection of Red objects.
- An optional range of frequencies and wavelengths representing a spectral color. These are only approximations as different sources will have different ranges, and people will perceive the boundaries to be at different points.
- Optionally set(s) of color coordinates, referring to a specific color.[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 used by computers and video displays. Normally sRGB is used.
CMYK color model: The coordinates in CMYK space as commonly used during color printing. Colors represented by CMYK coordinates vary greatly between printers depending on the inks used.
HSV color space: The HSV space is a transformation 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.
- Examples of other 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.
- Extensive information on color coordinates can be found here here.
- However some specific colors fall outside of some color spaces and standards, and can therefore not be represented in that color space – e.g. many bright/luminous colors can not be represented in CMYK for printing.
