I just found this information out yesterday. Ive been designing my tat for 2 years now and deciding on where to put it. Now that ive figured that out Ive visited some shops and talked to some of the artists. One of them told me that if I am allergic to fish (I am not formally allergic to shellfish but it makes me nauseous and gives me a tummy ache) they said I shohld avoid red dye. Is this true? Has anyone heard of this before?
They also told me about iodine but I believe I am ok with iodine. Red inks comprised most of my tat designs so im pretty bummed out if it is indeed a guarantee that id react to the red.
