I found a local source of Valejo and Pro Acryl paints at a local game store. I started looking for RGB values of their colors to try and match the color I was looking for. I googled Pro Acryl RGB and came up with a website
www.scalemates.com that has paint chips of many different brands. These could be used for this technique by the original poster. Scalmeates even cataloged the names of Floquil paints but unfortunately didn't have the actual RGB colors of it. Oh well, now to look for another source of C&O Enchantment Blue.
