Suture dye in tissues
Sutures that dissolve do so completely and leave no residue. No dye will remain after enough time has passed.
Purple absorbable suture
Sutures that dissolve like the one you describe will not stain the tissues. While its strength will diminish in several weeks, it will take several months for the suture to completely dissolve.
