Color grading in echidna reports: for all VSC themes

[dappconsulting]

Not sure if this is only my VSC misbehaving, but since I'm using a dark theme from VSC, I dont see the color grading on the reports. And when I switch over to light themes, still no color grading.
This is not a problem at all as its obviously still possible to see where there's no test coverage, but just a bit slower.

Is this just a me problem, or?
