[Shell] Default color for parameter value is very weak

Description

Outline the issue here: Default color for parameter value is very weak. More distinct color is better especially for users who use terminal with black/grey colored background. It’s good to pick a color from standard 16 color pallet considering many terminal configurations.

It is in the title [Shell] and also you can tell from the prompt in the screenshot az>> is the prompt within az interactive. But you are right–nothing in the original post makes that clear. I just happen to know the history of the issue 😃
