Start with the work, then ask a different question
Colour can organise a tattoo as decisively as its outlines. In the studio’s 16 October selection of Lil Dich’s work, the accompanying descriptions move between botanicals, expressive lines and architectural references. Those are useful starting points for discussing a design: which shapes lead, where colour carries the image, and what you want to see when you look at the piece.
A photograph cannot tell us which pigment molecules are present. It cannot turn a visual preference into a chemical assessment, either. That distinction matters when a question about a colour tattoo becomes a question about sunlight.
“Will it change?” and “What does that change mean?” deserve separate answers.
A pigment experiment is not a forecast for your arm
A 2025 study by Aubry and colleagues investigated Pigment Orange 13 under accelerated ageing conditions. Researchers exposed a pigment suspension to simulated sunlight and examined its chemical products and effects in a human keratinocyte cell model. Some soluble products generated by ageing were more cytotoxic under the tested conditions. [1]
That is evidence about a particular material and experimental exposure. It is not a study following people with tattoos through years of ordinary life. The suspension, the exposure and the cells do not reproduce an entire healed tattoo in skin. The experiment cannot supply a personal fading timetable or a probability of illness.
The useful question is narrower: can light change this pigment’s chemistry, and do those changes affect the laboratory endpoints being measured?
Even a familiar colour name covers different chemistry
A further paper from the same research group, published in 2026, compared pigment behaviour under artificial ageing. Its abstract describes different responses: Pigment Red 254 was photostable under the tested sunlight conditions, while Pigment Red 122 produced toxic photoproducts. [2]
We consulted the abstract, not the full paper. These results therefore support a limited point: “red” is not a sufficiently precise chemical description for a blanket statement about all red tattoo inks. Nor does stability under one experimental condition establish that a material is risk-free.
That distinction matters when a headline presents an entire colour category as safe, unsafe or guaranteed to last.
Three questions to ask of a research claim
Before applying a study to your own tattoo, look for three things:
- What was actually tested? A purified pigment, a finished ink, cells, an animal model or people with tattoos?
- What counted as a change? A chemical breakdown product, a cell response, a clinical symptom or a visible difference?
- What remains unknown? Does the experiment describe the conditions you are asking about, or does that connection still need research?
A useful explanation should keep those distinctions visible. A dramatic laboratory result does not automatically describe everyday exposure. Equally, an experiment that did not detect a particular effect cannot certify that every possible effect is absent.
This is also why a photograph of an attractive healed tattoo and a laboratory paper answer different questions. One can help you discuss appearance. The other can investigate a defined material or mechanism. Neither should be presented as a substitute for the other.
What to do with this information
For healed tattooed skin, the American Academy of Dermatology recommends broad-spectrum, water-resistant sunscreen with SPF 30 or higher, reapplied at least every two hours outdoors. Its guidance also advises against tanning beds. [3] These are practical skin-protection recommendations; they are not a promise that a tattoo will remain visually unchanged.
Fresh tattoos are a different situation. Use the studio’s aftercare information and the instructions discussed for your appointment rather than treating this research article as a healing protocol.
Bring a design question, not a demand for a guarantee
If colour is central to your idea, start with work you connect with. Lil Dich’s artist portrait offers one route into that conversation. Explain which elements interest you: the arrangement, the palette, the subject or the relationship between dark and light.
Then add the intended placement and approximate size. The tattoo enquiry guide explains how to prepare that information.
A useful conversation leaves room for both artistic judgement and the limits of current evidence. We can take colour seriously as a design decision without pretending that research supplies a lifetime guarantee.
