Are you familiar with Pantone? Each year they pick a colour that is to be the signature colour for that year. This is the colour for 2014.
Just for fun I took my quilt and uploaded it into Chip It!, the website that turns any picture into a palette and gives you 'chips' of all the colours in your quilt, to see if I had any orchid. I am close with the purple I have on the left of the quilt.
This is really helpful if you have a print fabric and want to pull out the colours in it to correspond. Sometimes it is hard to see what is in there. Or the same with a photograph. You just upload the picture and it pulls out the colours for you.
The quilt above just got accepted into the AQS Lancaster show=) Go and have a try with Chip It!, bet you can't stop with one picture=)
