What I try to do is if the website offers it, match colors through their systems. My first stop is equilter, here is the current Hoffman color challenge, you can click on a color in the fabric and it will show you other fabrics that match. More or less. Certain colors are "in" but even within the same label there may be differences much less from between brands.
