Is it possible for you to implement text colors in your text editor?
In our previous test tool, I used it a lot.
Thank you for your suggestion!
Actually, the Testiny editor is designed to also support colors in the future. It’s just a matter of making sure, the used colors fit nicely into the Testiny themes, i.e. that users don’t write somebody in the light theme that no one can read in the dark theme 
Would you need arbitrary colors or would a fixed color palette be good enough for you?
If somebody reads this request and also would like to have this feature, make sure to vote for this topic. We do consider the number of votes for feature requests in our roadmap and priority planning.
Best regards,
Alex
