It's possible that I misconstrued the meaning of your words; not being a native English speaker myself, this happens on occasion. I was going off of the word "vibrant", which I understand to mean among other things "vital" and "energetic". The opposite of that is to make something sickly and weak.

I was more objecting to your use of the word "diverse". And frankly these days "vibrant" has almost no meaning beyond being an applause light.
