Chat messages not very readable if the person has light colors

[sjoerd]

Messages from a user with yellow as one of its two colors aren't very readable in the chat activity, because then the messages typed by this user have a yellow background with white letters.

I'd like to add that "not very readable" should be "totally unreadable". Is there a text color widget that could be added to switch the color of text on the page?

It's basically the yellow background that has readability issues with the white text. I'll try increase the font size, since bold white text is readable on the yellow.

Eben, this problem occurs in Chat with white text on a yellow background. I don't want to change the font size or style for this one issue, but it is difficult to read.

One solution would be to choose a text color depending on the background. The following lines solves this for me:

  color_fill_rgba = Color(color_fill).get_rgba()
  color_fill_gray = (color_fill_rgba[0] + color_fill_rgba[1] + color_fill_rgba[2])/3
  ...
  if color_fill_gray < 0.5:
      text_color = COLOR_WHITE.get_int()
  else:
      text_color = COLOR_BLACK.get_int()
