Colorizing Project Bar

I love Asana. It is very helpful for the job I do. I use the “favorites” feature to organize my projects in the left hand black Project list (see attached). To group my projects (started projects vs. not started, and present projects vs. past) I create a blank project as a divider between sections. Is there a way to change the color of the bar from black to another color?

Unfortunately not, you can’t change the entire bar, just the colour of the project (as shown on the left) like you’ve already done.
