A 28-year-old female diagnosed with a case of persistent trophoblastic disease was transfused 1 packed red blood cell in view of bleeding per vagina. The blood bag was issued after pretransfusion testing as per the departmental standard operating procedure. The blood unit along with the blood transfusion set was returned to the transfusion medicine department as the patient developed reaction to the transfusion. The purple hue on the administration set was noticed by the transfusion medicine resident while looking for hemolysis [Figure 1]. It was also noticed that the blood bag and the blood in the drip chamber had no discoloration except in the tubing of the administration set [Figure 2]. Sample from the tubing was collected and was found to have no discoloration or hemolysis. The sample from the tubing was sent for Gram stain which showed no microbial growth ruling out bacterial contamination. It was also found that the discoloration completely disappeared on repeated flushing of the tubing with normal saline. The same discoloration was observed with all the other infusion sets from the same batch (lot no-12, manufactured by P.H. Medisurge, Ahmedabad, Gujarat, India) and not with that of other batches. On inquiry regarding the same, the company officials explained that the particular batch of BT sets could have undergone the usage of a different colored tone during the manufacturing of the tubing of the set. According to the company, they usually use an yellow tone or transparent tone in the tubing, but in the particular lot of sets, they mentioned the use of a different tone color possibly a different shade of the blue as the tone material in the tubing. The author suggests the use of uniform color tones in all the BT sets and mentioning of the same in the instructions given in the BT set packs to avoid unnecessary confusion and concern while administering blood through the blood administration sets.{Figure 1}{Figure 2}
