When I am out and about I try to notice color combinations that I see, somtimes in nature, but most often in what people are wearing or unusual combinations in fabric prints. I would never have thought to put pink and brown together in a baby quilt but it turned out to be one of my favorites so far. To help with contrast I ask my husband, he is color blind to most colors and can see the contrast better than I can even with the red or green filters.
