CMYK
The CMYK color space is not registered in Color by default
Properties
Name: cmyk
White Point: D65 / 2˚
Coordinates:
| Name | Range* |
|---|---|
c | [0, 1] |
m | [0, 1] |
y | [0, 1] |
k | [0, 1] |
* Range denotes in gamut colors, but the color space supports an extended range beyond the gamut.
The CMYK color model is a just like CMY except that it adds an additional channel k to control blackness.
The CMYK color space, as ColorAide Extras has chosen to implement it, is directly calculated from the sRGB color space, and as such, is based off the sRGB primaries.
Channel Aliases
| Channels | Aliases |
|---|---|
c | cyan |
m | magenta |
y | yellow |
k | black |
Input/Output
CMY is not currently supported in the CSS spec, the parsed input and string output formats use the color() function format using the custom name --cmyk:
color(--cmyk c m y k / a) // Color function
The string representation of the color object and the default string output use the color(--cmyk c m y k / a) form.
>>> Color("cmyk", [0, 1, 1, 0])
color(--cmyk 0 1 1 0 / 1)
>>> Color("cmyk", [0, 0.35294, 1, 0]).to_string()
'color(--cmyk 0 0.35294 1 0)'
