Since 2000, Pantone has selected a colour of the year, that has wide influence on colour trends and all kinds of products ... including fabrics, of course.
Pantone's colour of 2012 is Tangerine Tango.
Tangerine Tango Quilt Challenge ...is an online challenge (you make an item according to the challenge criteria, and post photos of your entry to a Flickr group) that celebrates the 2012 colour of the year in a quilted item. It runs for two months, until 2nd march 2012.
Could be fun - anyone who has a tangerine paint chip for the current Fairholme Quilters' challenge would be streets ahead.
