It’s not an issue itself, more like a suggestion, I think it’s not possible to change the color of the progress bar component, only having those 4 options (success, info, warning, danger).
From my point of view, it doesn’t make sense don’t allow to customize the color, it doesn’t seem to be a complex feature to develop but it might be.
I think, using template it would be possible, as I’ve been working with popover template and I could customize colors and things. If not, a fast and useful fix could be to add and attribute to accept color in hexadecimal pattern.
What do you think about it?
Thanks for the great work!
