I think it is a "born with it" issue. I have a great eye for color, I have been told by many people. I find it a natural kind of thing. I go to a fabric store and easily pick fabrics that go together, often, colors that others would not think to put together. It seems to be a natural kind of thing. I am so grateful that I have this ability; I see others who struggle so with deciding on colors. I also think that there are people who have the knack, but lack the confidence to trust their judgment about what colors go with what.
