Color text in markdown

[jeppeutzon]

@bkeepers : FYI people are continually asking for coloured text in this closed issue:

#369

Hi, thank you for starting this new issue. I would absolutely appreciate that feature. Thank you

[ddopson]

+1000, which is a roughly accurate summation of six years worth of continuous +1 posts on issue #369, most of which weren't noticed due to that issue being closed for most of that time. (I'm exaggerating only slightly; the real number is 76 posts)

Please fix this and sunset one of my most popular StackOverflow questions (another +358 upvotes and counting): https://stackoverflow.com/questions/11509830/how-to-add-color-to-githubs-readme-md-file

Color is an important design feature for many CLI tools, including my underscore-cli tool for hacking on JSON data, and thus, it's important to be able to include properly colored output examples in the documentation.

Currently, the ONLY way to accomplish this is with a screenshot:

Screenshots are inferior to natively colored text. Beyond the minor inconveniences of being cumbersome to create / edit / maintain, and slower for browsers to load, screenshots thwart readers from copy/pasting key snippets of text, such as the command that was executed in the screenshot -- this makes the documentation less usable, and the potential work-arounds are all very ugly.

Another use-case from issue #369: There's a reason you support auto-colorization of code blocks --- coloring text is crucial for facilitating our eyes to parse it faster. However, there's no fallback story for tail languages and other structured text formats that aren't in your list.

Many, many projects would benefit from being able to tastefully color the structured text in their documentation.

I am here to add my support to colorization in Markdown. Colors are an essential part of communication and we are in 2021, not in 1981 with monochrome displays.

[aarakelian]

Please, make colors happen!

It is crucial indeed! It's been 7 years for god's sake...

One of examples where color text in markdown is useful is Terraform plan reviews.

Consider attaching Terraform plan into GitHub tickets, issues or pull requests. Having TF plan is useful, makes it easier to review pull request, but.. it is plan text, no colors at all.

You can abuse the support for diff. I pipe it through this function (zsh/osx):

format_plan () {
	awk '
    /Terraform will perform the following actions:/ { found=1 }
    /------------------------------------------------------------------------/ { found=0 }
    // { if (found) { print $0 } }
  ' | (
		printf '<details><summary>Plan for %s</summary>\n\n```diff\n\n' "$1" && perl -pe 's/\x1b\[[0-9;]*[mG]//g' | sed -e 's/^\(  *\)\([\+-]\)/\2\1/' -e 's/^\(  *\)~/!\1/' && printf '```\n</details>'
	) | pbcopy
}

At least, GitHub could create a custom attribute (<span data-color="red">Red</span>) for example. This would be great as you don't have to use style attributes anymore anymore. It would be easy to style these with some javascript.

Recap of two hacks methods provided to do this

Diffs

```diff
+ Green
- Red
! Orange
@@ Pink @@
# Gray
...

It's okay but no inline text I guess

And we also have those symbols. but we can disguise them by doing + Green + instead of + Green for example

[Rikj000]

Idk what GitHub is waiting for, all IDE's I use support coloring in MarkDown..
The hacks described above "work", but should really not be considered as a "fix". The solution is way too dirty for that...
It's 2021 guys, we'd like some proper

Damn, I am surprised at how many people have been asking for color to be implemented into the GitHub markdown preview, and how long they have been asking for it w/o reply. When a company is new, they are so quick to cater to a customers needs, but when they get big like GitHub did, they can honestly care less. Its not that I think they should insert color into there markdown engine, but at the very least give a quick one liner reason as to why they won't implement color into MD rendering engine.

If I had to guess as to why they don't implement color, I would say it is because, they are the only one with black and white text & oversized headers. There markdown, generates a README view that is unique onto GitHub. Any of us can look at a dot MD document on GitHub, and know we are reading something in a GitHub repository. It is so unique and custom, that I see editor extensions that generate markdown in the same format as GitHub does. There MarkDown is a unique trademark of there site. Which makes since because I know that, (75% ) or more, of the time I spend in GitHub, is in my own, or someone else's, README.md documents. I believe they are MS now, which are like the contemporary marketing gurus.

EDIT:
Just wanted to point out that using something like
+ some-text +
- some-text -
# some-text #
* some-text *

wont work because most of the syntax you are suggesting is already being implemented in Markdown. You need something unused
like:

$[1] SumText $

Where 1 equals a set of numbers ex(1-8) or (1-4) or whatever...
each number is a different color. It would take some ingenuity to implement. Many of the commonly used shorthand's are alreadt being implemented in contemporary markdown.

Could you please some support for colored text in markdown?
