I'm a beginning quilter. Just learning to make pot holders. However, I have been an artist and interested in color all my life.
And, I came across this amazing color site the other day:
http://colorschemedesigner.com/#
Go to the top of the page and click on 'vision simulation.' This shows how various colors appear to people with different types of color blindness.
I have never seen this information anywhere before. I hope it helps with the quilt.
