Generation status color must not be grey
When a generation is in proccessing, the status zone in header bar is grey. But grey is the color for "no answer" in rudder, and it's also the color that status is displayed when the page is loading. So if users don't click on it, they may thing that it's a problem.
When a generation is in process, we should either keep previous status color (ie green if it was green, red if it was red) or at least use rudder color for "pending", ie blue.
I propose to correct in that ticket only to blue if it's simpler.
