Points with multicolor text

🐛 Bug

I cannot add points with multicolored texts.

For me the example code provided in napari fails with the same error as in the code I was working on.

Hi @andy-sweet thank you very much for your help so far. Now I am using the text multicoloring but I was unable to color the text of different clusters of points in the correct order. I created a discussion on image.sc https://forum.image.sc/t/adding-multi-colored-text-to-clusters-of-points/70451/1 I just wanted to make sure it reaches you since this issue has already been closed.
