### What happened

In the tree view, the status color for deferred is very difficult to distinguish from up_for_reschedule and is generally not very distinct. I can’t imagine it’s good for people with colorblindness either.

### What you expected to happen

I expect the status colors to form a distinct palette. While there is already some crowding in the greens, I don't want to see it get worse with the new status.

### How to reproduce

Make a deferred task and view in tree view.

### Anything else

I might suggest something in the purple range like [BlueViolet #8A2BE2](https://www.color-hex.com/color/8a2be2)
