i read everything i found when i search that error. To solve it firstly i remove python 2 then i opened the directory
python\Lib\site-packages\colour\
i deleted everything in it then i clone git repository
`cd ../`
`git clone https://github.com/vaab/colour.git`
`cd colour`
after that i tried
`python setup.py install`
i get that error :
Missing version information: running './autogen.sh'...
'bash' is not recognized as an internal or external command,
operable program or batch file.
It seems that ``./autogen.sh`` couldn't do its job as expected.
Please try to launch ``./autogen.sh`` manualy, and send the results to the
maintainer of this package.
Package will not be installed !

after that
`autogen.sh`
and try again
`python setup.py install`

installed and i tried example it worked
