Changing workspace/timeline color in Animate CC 2019

Just downloaded the latest version of Animate CC. The timeline and the stage background is a dark grey. I don't mean the stage, I mean the area outside the stage. It is very hard for me to see this dark color. Is there a way to change this like there is in other Adobe apps? Looking in preferences there is (or at least I didn't see it) no option to change this.

Thanks in advance for any help.
