Please switch to dark mode
Steps:

1. Circular progress or linear progress
2. Soft variant (default setting)
3. dark mode

Current behavior

The track is nearly invisible, and the moving blue progress is too dark.

It becomes even worse if it is shown on a modal:

Expected behavior

Previously I used 5.0.0-alpha.84 and the color was easier to identify.

Not sure if this change is intended.

Hey, there @mazstars; thanks for opening this issue! There's definitely room to improve aspects of Joy UI's colors. I'd recommend fixing it locally on the component in your app for now, given that the color the progress-related components use is shared across all of them, and touching on this is out of priority for us at the moment (as the team is focused on Material UI's v6). I'll keep the issue open, though, and we'll circle back when possible!
