Jinny Beyer had a color theory book - Color Confidence for Quilters.
where she matched the colors "exactly" in the focus fabric and then added "bridging" colors between the exact matches - and then she only "used" the bridging colors.
Example: I have red-orange and blue-violet to match - I use red-orange, red, red-violet, violet, and blue-violet in my color sequencing - and then only use the red, red-violet, and violet
From her pictures, the effect was more interesting than using exact matches.
The book seems to be moderately priced on the used-book venues.
