At present, the app doesn’t support text color and highlighting. The feature can be added using markdown-it-attr. Also adding markdown-it-attrs can make the app more flexible to styling.
I use bold. font color and highlight to denote importance of the words in my notes. Here is my general workflow:
Reseach and compile info (text, images, tables etc)
Reorganize the info (if there are overlapping sections, merging sections of info)
Summarizing (this is where I start running into trouble)
Build presentation and talking notes
Talking notes Summary (this is where it all fall apart)
@ #3 in other apps I starte to Bold and then in final step I highlight... #5 is much the same but for memorizing a speach... I bold imporatant key words and then I red fornt, then finally highlight key words I keep forgetting.
Maybe it's just not meant for this kind of work flow... which is ok... can anyone suggest another app better suited to this kind of workflow?
I know this is an old question, but in case someone else stumbles onto it like I just did as a brand new user of Joplin (I'm trying to get rid of Evernote which I mostly like, but the constant nagging and inability to sync more than 2 devices - I only need 3, so I don't really want to pay $10/mo for one more device...) I just wanted to mention that the plugin called "Text Colorize" makes coloring text pretty easy once you get used to it. I like that it allows you to save colors too. I don't color too much text in my notes, and I don't use too many different colors, but when I do, it's important to me, so this plugin makes Joplin work for me. At least so far. To install the plugin, go to Preferences -> Plugins and then search for Text Colorize. Click it's text link after it's installed to get taken to an instruction web page for how to use it. Also, I had to quit Joplin and restart after installing it to get it to work. I'm on an old 2009 MacBook Pro running OS X 10.13 if that helps. Have a good one.
