I like to pick out my own fabrics. One of the ones I made I did it in Blues and Yellows. I had several fabrics that had both the blue and yellow in them and then several each that read blue or yellow (tone on tones, blenders etc) I think it came out looking really nice.
My recommendation is pick out 2 or 3 colors that you want in your quilt and find a couple fabrics that have all the colors in it or at least two of the colors and then varying shades of your colors to blend with it.
This is a quilt I made as a wedding gift for my eldest brother
