:py:mod:`ImageColor` Module
|
|
===========================
|
|
|
|
The :py:mod:`ImageColor` module contains color tables and converters from
|
|
CSS3-style color specifiers to RGB tuples. This module is used by
|
|
:py:meth:`PIL.Image.Image.new` and the :py:mod:`~PIL.ImageDraw` module, among
|
|
others.

Color Names
|
|
-----------
|
|
|
|
The ImageColor module supports the following string formats:
|
|
|
|
* Hexadecimal color specifiers, given as ``#rgb`` or ``#rrggbb``. For example,
|
|
``#ff0000`` specifies pure red.
|
|
|
|
* RGB functions, given as ``rgb(red, green, blue)`` where the color values are
|
|
integers in the range 0 to 255. Alternatively, the color values can be given
|
|
as three percentages (0% to 100%). For example, ``rgb(255,0,0)`` and
|
|
``rgb(100%,0%,0%)`` both specify pure red.
|
|
|
|
* Hue-Saturation-Lightness (HSL) functions, given as ``hsl(hue, saturation%,
|
|
lightness%)`` where hue is the color given as an angle between 0 and 360
|
|
(red=0, green=120, blue=240), saturation is a value between 0% and 100%
|
|
(gray=0%, full color=100%), and lightness is a value between 0% and 100%
|
|
(black=0%, normal=50%, white=100%). For example, ``hsl(0,100%,50%)`` is pure
|
|
red.
|
|
|
|
* Common HTML color names. The :py:mod:`~PIL.ImageColor` module provides some
|
|
140 standard color names, based on the colors supported by the X Window
|
|
system and most web browsers. color names are case insensitive. For example,
|
|
``red`` and ``Red`` both specify pure red.
