still be a bit green, and starting to yellow.

Same. Bananas, avocados, and artichokes all get this weird but similar taste when they get ripe beyond the point I can enjoy them. Idk what it is exactly or even how to describe the taste, but some people seem to either not notice a difference or actively be seeking it out.

Most ready made guacamole always seems to have that same flavor. Honestly not sure if there's even a name for it, but it almost makes me gag.
