Limiting font color while creating a post?

[Untuvakana]

Is there a way to limit a font color while creating a post to black only? I'm also interested with other limitations like Normal font is 18px only and Headline is 28 etc.  Is there way to do it for example using powershell or am I asking too much?

@Untuvakana you'd need to create a custom theme for the site then apply it but of course it would affect the whole site not just news posts. There's a video about how to do it here.

I have made several costum themes and I know the theme colors comes from that but then there are options for default colors in font color selection. Can I hide those?

I don't think you can achieve this with a custom theme. Currently SPO themes are quite limited when talking about customizing fonts
