B&W Mode or Colorblind Users Can’t Distinguish Between Stacked Datasets

[bbertucc]

Describe the bug

When I toggle to the black and white color preset or test the charts as a colorblind user, I can’t distinguish between datasets on the stacked charts.

Affected component/components

Stacked Charts

How to reproduce

1. Toggle on the B&W color preset
2. Visit any stacked chart
3. On hover, you won’t be able to truly distinguish between datasets.

I don’t think you really need a link

Logs are unnecessary because this is a UX problem

System Info

I was looking on Safari for iOS but I assume anyone would find this on all supported browsers.
