How to Add Duo Color Text In Center of Doughnut Chart in Chart JS

Can we hide this custom label using on hover event?

First of all thanks for all your educational video's. I have watched dozens of them the last month.

This is an interesting video.

I want to style the default tooltip which currently uses an array with push to get multiple lines with information from one dataset.
I want the values to be bold, so in the tooltip I want to create a bold font for: C, 40%, 49998 MB and 8416 MB

Drive: C
Free disk space: 40%
Total disk space: 49998 MB
Free space: 8416 MB

Could this duo color text method be applied to the default tooltip?

I am aware of the HTML tooltip (did not test it yet) because I expect all kinds of other difficulties with the HTML tooltip, like positioning the tooltip, positioning the arrow down, tooltip getting behind chartarea etc.
