At Equilter they have a "match this color" option you can search with. Maybe you can find something from the same collection?
It is best of course if they still have the fabric you used on site, then you just click on the color you are trying to match. I brought up this sale fabric just so you didn't need to search through where the Match Color thing is. Just click on a bug and it will change the color search fabric!
