One way to match colors is to find a print you like the color combination of and use it as a guide. The print you use as a guide does not have to be one you use, it is just for the colors. Check for the color circles on the selvedge. You can use those to choose coordinating fabric. To get as many fabrics as you want to use choose colors of different value of the dots shown (or in the print if not dots.) I fell in love with a fabric for my granddaughter, used the dots for my coordinating colors, then ended up not using the original fabric.
