When getting a tattoo, the choice isn’t just about the design but also the colors. Most people opt for the classic black. However, red tattoos are also popular–for example, timeless designs like roses and hearts. But this color is said to cause allergies and rashes more than any other. Is that really true?

Red Tattoos Contain Mercury Sulfide
Researchers at the University of Graz examined 73 tattoo colors and published their findings in 2021: They found the often problematic metals nickel and chromium everywhere, but the dyes in red tattoos contained the most impurities. Additionally, they found mercury sulfide in them. “With this heavy metal, the risk of an allergic reaction is significantly higher,” says Dr. Alice Martin, dermatologist and co-founder of the telemedicine practice Dermanostic. “It doesn’t have to happen, but the likelihood is increased.”

Possible Allergic Reactions
Red tattoos are more likely to trigger allergic reactions than tattoos of other colors. The severity of these reactions varies from person to person. Mild redness may occur, and some people experience itching or burning skin. In severe cases, nausea, fever, or shortness of breath may occur. “These symptoms may not appear immediately but can manifest later,” warns the dermatologist. Depending on the severity of the symptoms, a doctor should be consulted. If possible, ask the tattoo artist to show the ingredients of the ink used. A targeted allergy test can then provide clarity and allow for appropriate treatment.
Those getting a tattoo for the first time naturally don’t know how their body will react. To be on the safe side, it’s advisable to start with a black tattoo. However, Dr. Alice Martin cautions: “Regardless of the basic components in the inks, they are all foreign substances to the body, and the skin can react allergically to any of them.” The dermatologist recommends avoiding tattoos altogether if you are prone to allergies or skin conditions like eczema or psoriasis.

Red Tattoos Are Harder to Remove
Heavy metals and increased allergy risk–there are several reasons to be cautious about the color red in tattoos. And when it comes to removing tattoos, this color is comparatively difficult. “Some tattoo colors are hard to laser off,” says Dr. Alice Martin, drawing from her extensive practice experience. “Red is one of them. The laser device has a harder time recognizing its color pigments than others.”
Are Red Tattoo Colors Banned?
Since 2022, many tattoo colors have been banned within the EU. The so-called REACH regulation (a strict chemical law) specifies which color pigments are allowed and which are not. Some pigments for red tattoos are included in this list. The market responded by developing new colors–without the dangerous ingredients. However, these are less common and often more expensive than conventional black tattoo pigments. So, if you still don’t want to miss out on colorful body art, you should thoroughly research your preferred studio in advance and ideally have a color expert handle the work.
