Do you have any scraps of it and the other fabrics left?
If yes, put them all together in a jar - add some detergent and water to it - shake and let set for awhile -
Come back in an hour or so - and see what happens.
Some fabrics seem to be resistant to picking up stray dye molecules. Others seem to be magnets.
If the colors seem okay after setting for a while, you are good to go.
If not okay - do what the experts suggest.
As far as that goes - if you did not wash the black and whites or other fabrics - some of them may also have issues.
I think it's Synthrapol that's suggested to pick up stray dye.
