Differentiate colors in workspace summary (project summary)

The small dots with class l-1 are not very different from class l-0, I was seeing the screen a lot but after a long time (~ 12 weeks), I just realized that it was two different dots, I would recommend changing the colors for the one with class l-1 (others might change as well) to make a visual difference from a far.
