My issue with the background color was how to make a TextAttribute to set the background color of individual characters, not the overall background of the text.��

I succeeded, and Pharo 8 has a background text attribute - at least using Rubric - see��https://github.com/pharo-project/pharo/pull/5326

Christopher - thanks for the hint on doing background colors based on theme. I did do it for the two main themes, and did not try out the larger set of themes.

I needed it because I am working on an in-image pillar renderer for class and package comments, and I wanted to be able to do the inline code as done in github markdown.

There is a preview of this at:��https://github.com/kasperosterbye/PillarRichTextRender

If you want to consider changing background color that takes into consideration the theme background (e.g. dark or light themes), this code (see it on GitHub)��can adapt to it:

normalColor := Smalltalk ui theme backgroundColor.
green := normalColor mixed: 0.8 with: Color green.
red := normalColor mixed: 0.8 with: Color red.

I didn't really test it with all possibilities of themes, however.��

You should use TextMorph.

What about:

|| t |
t := TextMorph new.
t backgroundColor: Color blue.
t contents: 'Hello'.
t lock.
t openInWorld||
