Red-green colorblind accessibility issue with coverage report

[kristinnbragi]

I was going over code coverage results with a developer who has colour blindness and discovered that the tool is not accessible for red green colour blindness. Line highlights are especially hard to differentiate due to the desaturated colour. A natural fix would be to include symbols as a supplement.

I totally understand that this is an issue.

• Do you have a concrete idea for "include symbols as a supplement"?
• Would a different color scheme be more helpful (e.g. blue/yellow instead of green/red). What would be good colors?

Not really, although a simple + or - would work, it might also be misleading. Another tool, Bullseye, uses these icons for example:

Definitely! I don't know what colors would make sense that would support all types of color blindness. Ultimately, the best solution would be to offer the user to choose their own color scheme

I added a new report type Html_BlueRed in version 5.1.19
To use it, add the following command line parameter when executing ReportGenerator: -reporttypes:Html_BlueRed

Here you can find a sample report:

Hope this helps!

Hello.
Could you please clarify what type of reports I can use for summary report to resolve the same trouble?

There no separate Blue_Red summary report yet.
But I can add this in the next release.

Thanks a lot

@vzhik54
I just created a sample report: https://reportgenerator.io/resources/reports/Html_BlueRed_Summary/summary.html

Does this work for you?

The next release will contain the new report type Html_BlueRed_Summary.
