Request: (Low Priority) (Nav Unification) (User Feedback) More variations on color scheme?

A user shared their insights about WordPress.com color scheme.

A bit of context, they got caught off-guard with our unified navbar and disliked the Classic Dark color scheme since the contrast is too high (white-on-black). I'm not sure what's going on, because their dashboard color scheme was set to Classic Dark when I did initial check, so to have the white text on black background should be expected since Calypso days 🤔 I would say they saw the changes, and they had knee-jerk reaction with the colors (so not directly related with Nav Unification. However, I'm tagging this issue with Nav Unification just for clarity.)

Their feedback are:

- Is it possible to have color palette instead of the pre-set color scheme that users can set on their own?
- They commented, "I like the Classic Bright the best, because dark text on neutral background is simple to process -- but I prefer a gentle mossy green for highlights like in Ectoplasm." However, I must add, they didn't like the blue top bar 😅

This is the look they are looking for:

This is something that non-urgent and I write this for tracking purpose. Thank you so much, folks!

No files, tests, or entry points are identified. Start by reviewing the existing dashboard color-scheme implementation and the linked screenshots, then define the palette or customization scope. Done should include an agreed design and a clear implementation target.
