Trouble getting text style changes to “stick”

I can access where to change font and color of text, but my text color changes have no effect. I can change the typeface. I am using Dark mode. Is there a trick to getting scrivener to accept my change to text color?
Thank you!

iOS Scrivener Dark Mode “desaturates” all text colours to grey. There is no way to get around this. You can see the colours if you switch to Light Mode.

Hope this helps!

Yes, that clarifies things. Thank you!
