Is effervescent a pejorative when describing a person [closed]

My colleagues and I have been talking about whether or not "effervescent" is a pejorative when used to describe someone.

To provide context, one of the people who works in my office is a high-energy and bubbly person but they aren't flighty or whimsical (they're grounded, well-adjusted). We've been trying to find the best adjective to describe them and wondering whether people thought effervescent sounded vaguely insulting.

Also, anyone have any good recommendations? Thanks!

Most dictionaries, as Collins, define effervescent with a positive connotation:

If you describe someone as effervescent, you mean that they are lively, entertaining, enthusiastic, and exciting. [approval]

• ...her winning smile and effervescent personality. America is the most intellectually, artistically and politically effervescent of nations.
