Can I add a border-radius to the tooltip label color box?

[gaminoff]

Is there a way to change it without creating a custom tooltip?
Tnx!

@gaminoff unfortunately there is no way to do that without either using an HTML tooltip or modifying the draw code. FWIW the code that does the drawing of the color boxes is https://github.com/chartjs/Chart.js/blob/master/src/core/core.tooltip.js#L674-L686
