Jinny Beyer had a book about color -
what she suggested - choosing a focus fabric with several colors - match the colors in the fabric - then use colors to "bridge" between the "matched" colors - and then to use the "bridge" colors instead the "matched" colors in the blocks.
Made for a much more interesting quilt.
When I first started, I was really into trying to match colors "exactly" - even if it was only a flower that was 1/8 inch across that one couldn't see from five feet away and didn't even "read" in the fabric from a distance.
