@Johann-S , the plot thickens -

After further research, I'm assuming the reason for the mixup with the color variable was intended to handle cases where the popover has a title:

The problem was that it affected all bottom-popovers, even those without a title.

This conflict can be solved by using the already existing title::before element to "cover" the existing arrow with the right color. I can quickly wrap a PR with this solution and let you decide what's best. What do you think?

Oh nice catch I didn't know that. Yeah sure create your PR but this time I'll CC @mdo because I don't know all the use case
