Critical acclaim with 100% on Rotten Tomatoes, and it was the #1 show on Amazon Prime while it was airing so I'd say it did pretty well. Certainly well enough that another season was immediately greenlit.
Sam Riegel “To try to adapt it to a single season is a daunting task. We were trying to find out if it was possible. Thankfully, we got greenlit for season 3.” So it looks like chroma conclave will be seasons 2 and 3
Riegel just recently stated that they have the material for at least five seasons of Vox. If it continues to be successful, I wouldn't be surprised to see something like season 4 as a transition season, with part of it including Tarryon Darrington, and Season 5 being The Whispered One.
Watched the first three episodes of season two last night.
The coordinated four dragon attack on Emon was brutal; the black and green (especially the green) using their breath weapons to kill anyone in the streets with clouds of poison gas and acid rain, the white blasting anyone trying to flee as refugees, and the red unleashing some kind of super breath weapon that penetrated the walls of the castle and filled the entire place with heat hot enough to melt stone was insane (seriously, it started out like traditional fire breath before concentrating into a Godzilla-style beam).
