I've noticed that colorist Joey Mason does not get enough credit for his remarkable efforts on Supergirl. He came onto the series as an unknown to Eric and myself, and I cannot tell you how amazed we were by the results. His attention to detail and efforts to affect mood and atmosphere with his coloring deserve credit. Not to mention his ability to produce on a very short deadline.
Here are two samples.
You can see how Joey introduced an emotional element to the story with the rising of the sun. It is subtle, but effective. This was not directed, he did this on his own. And he applied this level of storytelling throughout the entire series. Eric an I seriously cannot thank him enough for his efforts, and I think he deserves more attention than he is receiving.
