the pantone color of the year for 2013 was emerald. i'm not sure if they saw it coming or helped set the bar. is emerald a close enough match to mint green? https://www.pantone.com/pages/index.aspx?pg=21055

when it comes to color i think people like contrast, change and unique. emerald, or mint green, seems to offer those qualities. the 2014 pantone color is radiant orchid but i don't think i'm going to trend with that one. http://www.pantone.com/pages/index.aspx?pg=21129 i do like emerald though.
