What did you do?

$ go get gopl.io/ch7/eval
$ go test -run=Coverage -coverprofile=c.out gopl.io/ch7/eval
$ go tool cover -html=c.out

What did you expect to see?

Distinguishable text on html page with cover info

What did you see instead?

Uncomfortable color set. It is hard to read gray, green and red on black. Perfectly it would be cool to have color settings for cover tool.

#36685 is about accessibility for screen readers, not about look & feel.

[toothrot]

The decision of what colors to use must be considered from an accessibility perspective, so I feel like #36685 is the most accurate issue to use for discussing this. Please let me know if that is not the case.

Try this

$ go tool cover -html=c.out | sed '/background/d' > c.html
