Welcome to Xierpa. This is the stable 1.2 version which was developed by Petr van Blokland + Claudia Mens (buro@petr.com) and is maintained by Michiel Kauw-A-Tjoe. It is subclassed by the Museum Meermanno and American Express applications.

Color

Initialize the color from hex value, rgb or cmyk tuple.
Or from string rgb(r,g,b) or cmyk(c,m,y,k)
Initialize output format as either cmyk, rgb, hex or uhex
Otherwise raise an error

Note: There still are, though hardly visible, slight differences through the color conversions, e.g. Color('#b20071') returns the color #b20070.

Python example
Color('#b20071')
Color((178,0,112))
Color((0, 0.7, 0.26, 0.3))
Color('rbg(178,0,112)')
Color(('cmyk(0, 0.7, 0.26, 0.3)')
Color('#b20071','rgb')
Color('#b20071','cmyk')
c = Color('#b20071')
print c.lighten(30)
>>> #fe16a9
print c.lighten(30).desaturate(40)
>>> #d0439c
print c
>>> #b20070

Method	Attributes	Docstring or default value
CMYK		'cmyk'
RGB		'rgb'
RGBA		'rgba'
_b
_cmyk		The c.cmyk returns the color as e.g. rgb(254, 63, 103)
_g
_get
_getlist
_hex		The c.hex returns the color as e.g. #fe3f67
_negative		The c.negativebw returns white Color if the color is dark, and black if color is light.
_negativebw		The c.negativebw returns white Color if the color is dark, and black if color is light.
_r
_rgb	alpha	The c.rgb returns the color as e.g. rgb(254, 63, 103). Or add alpha as e.g. c.rgb(0.5) the color is returned as rgba(254, 63, 103, 0.5).
_uhex		The c.hex returns the color as e.g. 0xfe3f67
change	hue lightness saturation	The c.change() returns a new Color object, that is changed with lightness ranging [-100:100] (default is 0), saturation ranging [-100:100] (default is 0), hue ranging [0:254] (default is 0),
darken	v	The c.darken() returns a new Color object, that is darkened with with v ranging [0:100].
desaturate	v	The c.desaturate() returns a new Color object, that is desaturated with with v ranging [0:100].
lighten	v	The c.lighten() returns a new Color object, that is lightened with with v ranging [0:100].
mix	mix	The c.mix() returns a new Color object with mixed RGB channels. mix
opposite		The c.opposite() returns a new Color object with opposite r,g and b channels. E.g. if the red channel of the color is 203, it will be changed to 51
oppositehue		The c.oppositehue() returns a new Color object with the opposite color on the hue circle, while the lightness and saturation is unchanged.
saturate	v	The c.saturate() returns a new Color object, that is saturated with with v ranging [0:100].
setformat	format	The c.setformat() change the output format - if format is either cmyk,rgb or hex
setrgb	blue green red	The c.setrgb() set the red, green and blue channel of the color.
