You're welcome. People choose different colors for their own personal taste. I chose black because I have a black stand/canopy and white..ish substrate and I think it looks pretty sharp.
Edited to add...I did this in coats about 15-20 minutes apart from each other. Also, my first coat was a really fine mist of spray paint, in hopes the second coat would have something to cling to since the paint doesn't soak in to glass like it does wood. I hope that made sense...LOL
