Hey @dan
when you are looking into this I would say also in Light Mode the greyish color of the text is not optimal. I am not 70 but it is not good to read.
What I also find difficult is the color of the breakpoint “button”. It was blue in the past and now it is marked with white. The blue was better to see especially when you adapting your designs to lot of screen sizes and you quickly click through your screens to see what probably have to change
Only food for thought
I agree with @PMUK - Dark grey text on black …
As a cataract patiént, i would also love this. 
me too please and I am 85 and need it bigger
I can only agree with the above. It does slow down my workflow as I am trying to read the Components names. In the Pages tab and the Resources tab, the text is white against black in Dark mode and reversed in Light mode. Strange that Components is a grey on grey.
