Dashboard progress (incomplete jobs) bar should not be red when "almost" all reflected treatments are ok

Currently, when a job is not 100% complete, the progress bar that represents the completion is colored red. This red color gives the feeling of a failure, even when 99% of the process is OK.

Example here, with 1% error:

I suggested to @thomasbrand to change this color to green (or gray). I see different approaches:

• adapt the color depending of the completion status:
  • [0% - 20%] -> red
  • [20% - 50%] -> gray
  • [50% - 100%] -> green
• or simply green when > 0 %

Any ideas are welcome.
