Make a "More Colors" section for Word Online like in PowerPoint Online
This feature is now added to Word on the Web as well. Please have try it out and share any feedback on this thread. Thanks.
Is it really necessary though? You don't draw, you just highlight and change the font color. There's no main reason to have multiple color options. You know what I think would be better? You share one big color pallet. Like you share the same colors for OneNote as you do for Publisher, or Sway. And you can go to one thing, select a color, and then move to another app when finished and still use the same shade of hot pink or cyan blue. You could even access it from the Office365 home screen!
