I wrote this to generate a bunch of colorscheme previews from the highlight script at [here](http://www.andre-simon.de/doku/highlight/en/highlight.html) . YMMV.

highlight.py

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import os, sys
from subprocess import call

_THEMES = '/usr/local/Cellar/highlight/3.12/share/highlight/themes/'
_CMD = 'highlight {} --output={} -O {} --line-numbers --font-size {} --font {} --style {} -W -J {} -j {}'
_OUTPUT = os.path.join(os.path.dirname(os.path.realpath(__file__)), 'output/')
_TEST =os.path.join(os.path.dirname(os.path.realpath(__file__)), 'test/') 

_JAVA = 'Picture.java' 
#_PYTHON = 'picture.py' No python test file yet

def highlight(src_file=None, output=None, fmt='rtf', size=24, font='Courier', style='anotherdark', wrap=55, linenumpad=3, *args, **kwargs):
        """docstring for highlight"""
        if not output:
            output = os.path.join(_OUTPUT, '.'.join([os.path.basename(src_file),style,fmt]))
            if os.path.isdir(output):
                os.makedirs(output)
        command = [str(c) for c in _CMD.format(src_file,output,fmt,size,font,style,wrap,linenumpad).split()]
        call(command)

if __name__ == '__main__':
    themes = os.listdir(_THEMES)
    colors = []

    for theme in themes:
        colors.append(theme.split('.')[0])
    
    for c in colors:
        highlight(src_file=os.path.join(_TEST,_JAVA), style=c)
