tmTheme Color Convert

=====================

Many [TextMate](http://macromates.com/) color themes were designed on Mac

OS X, which used the Generic RGB color profile and a gamma of 1.8 by default.

This results in the colors being darker if used directly on Windows.

For portability and compatibility with other editors and operating systems,

it is better to use sRGB.

This script will convert the color values in a tmTheme file from Generic RGB

to sRGB, optionally applying simple alpha blending with the foreground and

background colors (for TextMate 2 themes before [this change][blend]).

I wrote this while working on a [blog post][post] about the effects of color

management on themes in text editors.

Usage

-----

The scripts are written for Python 3.

`tmcolorconv.py` takes a tmTheme file and converts the color values from

Generic RGB to sRGB. A gamma value to be used for the original file can be

supplied, and optionally colors with alpha values can be blended with

foreground/background color instead of copied.

    usage: tmcolorconv.py [-h] [-g GAMMA] [-b] infile outfile

    Convert Generic RGB to sRGB.

    positional arguments:

      infile                input tmTheme file

      outfile               output tmTheme file

    optional arguments:

      -h, --help            show this help message and exit

      -g GAMMA, --gamma GAMMA

                            input gamma (default 1.8)

      -b                    blend alpha

`mkconvmatrix.py` is a playground for working with color space conversions. It

was used to compute the `GenericRGBtosRGB` matrix used in `tmcolorconv.py`.
