Grey text of the Cheastsheets is hard to read when printed about cheatsheets

[rougier]

So this means working on the cheatsheet.tex file and removing any harcoded color in favor of variables such that we can have a switch to choose one specific set of color. It's not too difficult to do but I'm a bit busy until mid december. If anyone want to give a try...

Thanks. Which part exactly are you referring to?

Maybe an example will help

As an example, I have put 3 jpg below, based on the cheatsheets.pdf and the beginner handout files

• a jpg taken directly from a screenshot of the pdf open in Acrobat: quite readable!
• a jpg from a picture of the printed pdf: the picture looks even worse than what the eye can see on the printed version. Note: it's printed on reasonably white paper (that is, not grey looking recycled paper), and a heavy duty professional printer. The actual printed page is white, not the dirty grey of the picture, but the printed grey text is hard to read
• a jpg from a picture of the printed pdf of the beginner handout: same paper/printer and camera. Characters are bigger, but I think that the style used (black on light grey) is more readable (when printed)

Thanks, I see your point now. We could have a different set of colors with higher contrast for printed cheets or we could a post-processing on the PDF to enhance contrast. I imagine there are some tools to do that but I don't know them.

I think a "printed" stylesheet is the better route in terms of accessibility, cause we might also want a high contrast web version too.

I won't have time 'til December either, but if anyone else wants to take a stab, I've been doing this in a paper so I have a style file notation.sty with a whole bunch of definitions:

\definecolor{total}{HTML}{248EA6}
\definecolor{fiber}{HTML}{E30B5C}
\definecolor{base}{HTML}{7924AB}
\definecolor{section}{HTML}{03C04A}

and then use the following to parse my file to build a python dict to keep my colors in sync between latex and python

import re

sub = re.compile(r"\\definecolor\{(?P<name>.*)\}\{HTML\}\{(?P<color>.*)\}")

def build_colors(filepath = '../notation.sty'):
    colordict = {}
    with open(filepath) as f:
        for line in f.readlines():
            if groups := sub.match(line):
                colordict[groups.group('name')] = "#"+ groups.group('color')
    return colordict
