Yeah, I think “official reply” would be a natural progression for “add staff color”.
It shouldn’t be specific to Solved, since “official reply” is useful in virtually any context of a forum, and also with other plugins such as #plugin:voting
So how about:
- 
Rename “add staff color” to “official reply”, as that is a much more meaningful name that helps admins intuit what to use it for
 - 
Give it better, less extreme styling; something akin to what a few game forums are doing with all staff posts:
 - 
Don’t make me tack it on after posting. Add it to the post cog menu, alongside whisper etc.
 - 
Add a marker for it to the vertical slider.
 - 
Let plugins like Solved and Voting do their own special little things with it.
