That vibrant, multi-coloured tattoo might have felt like a brilliant idea at the time, but maybe now it feels more like a permanent reminder you’d rather forget. You’re ready for a clean slate, but you’ve probably heard the rumours: “You can’t remove colour tattoos,” or “Green ink is impossible to get rid of.”
While experts at Illusion Laser Clinic agree that removing a colourful tattoo is more complex than removing simple black ink, it is far from impossible. The key lies in advanced technology, deep expertise, and realistic expectations.
As the UK’s trusted experts in advanced laser removal, at Illusion Laser Clinic we believe in demystifying the process. In this guide, we’ll break down the science, the technology, and the honest answers to your most pressing questions about removing red, blue, green, and other challenging tattoo colours.
This is the fundamental question which most of the clients pose to experts at Illusion Laser Clinic, and the answer lies in simple physics. Laser tattoo removal works by sending a specific wavelength of light into the skin. This light energy is absorbed by the tattoo ink pigment (the “chromophore”), causing the ink particle to shatter into tiny fragments. Your body’s immune system then naturally flushes these tiny fragments away as often observed by skincare experts at Illusion Laser Clinic.
Think of it like this: a black t-shirt on a sunny day absorbs all colours of light and gets very hot. A green t-shirt absorbs most colours but reflects green light, which is why we see it as green. But this information is not for you to scratch your heads trying to figure out the physics but to help you understand that it’s the same with lasers. Different ink colours absorb different wavelengths of light.
The “difficulty league table” for tattoo colours generally looks like this:

This is where technology makes all the difference according to experts at Illusion Laser Clinic. For years, the Q-Switched (or nanosecond) laser was the gold standard. It works by firing light pulses in nanoseconds (billionths of a second), which is effective at shattering many ink particles, think of it as breaking a rock into pebbles.
However, for stubborn colours like green and blue, the game-changer has been the Picosecond laser (like PicoSure) according to experts at Illusion Laser Clinic. This next-generation technology fires ultra-short pulses in picoseconds (trillionths of a second). This incredible speed creates a powerful “photoacoustic” shockwave that shatters ink particles with immense force, thereby transforming pebbles into fine sand.
For difficult blue and green inks, Picosecond lasers are unequivocally superior as per experts at Illusion Laser Clinic. They can pulverise these resilient ink particles that nanosecond lasers often struggle to break down, leading to faster clearance and better results in fewer overall sessions. This is why a clinic’s investment in both Q-Switched and Picosecond technology is a huge green flag for a patient with a multi-coloured tattoo.
Yes, in most cases, it is absolutely possible to achieve excellent clearance on a red ink tattoo according to laser experts at Illusion Laser Clinic. Red ink responds very well to the 532nm laser wavelength.
However, red ink carries a unique and important risk: a higher potential for allergic reactions as often seen by experts at Illusion Laser Clinic. Some red inks contain metals like iron oxide, cadmium, or mercury. While inert in the skin, the laser process shatters these particles and can sometimes trigger a localised allergic reaction (intense itching, hives, or swelling) as your body is exposed to them.
This is why a thorough medical consultation and a mandatory patch test are non-negotiable at our Dorset clinic, especially for red tattoos. At Illusion Laser Clinic, we perform a test spot and monitor the area to ensure your skin and body react safely before proceeding with a full treatment.
This is the million-dollar question, and the honest answer is: it varies significantly. According to experts at Illusion Laser Clinic, anyone who gives you a precise number without seeing your tattoo is not being truthful.
As a general guide, our experts at Illusion Laser Clinic suggest that while a simple black tattoo might take 5-10 sessions, a complex, multi-coloured tattoo will almost always require more, often in the range of 8 to 15+ sessions.
The final number, as per experts at Illusion Laser Clinic, depends on a host of factors:
Best Case Scenario (new tattoo, professional artist, high-quality ink, fair skin):
Typical Case (3-10 years old, mixed quality):
Challenging Case (cover-up, dense ink, scarred):

Yes, skin tone is a critical factor in laser tattoo removal as often seen by experts at Illusion Laser Clinic. In fairer skin (Types 1-3 on the Fitzpatrick scale), the laser has a very clear target: the tattoo ink.
In darker skin tones (Types 4-6), the laser has two competing targets: the tattoo ink and the natural melanin in your skin. To protect the skin and prevent complications like hypopigmentation (lightening of the skin), the practitioners at Illusion Laser Clinic always use lower, gentler energy settings.
This means that for the same tattoo, a person with a darker skin tone will typically require more sessions to achieve the same result as a person with fairer skin as often seen by experts at Illusion Laser Clinic. In the hands of an experienced practitioner like those at Illusion Laser Clinic who is an expert in treating all skin tones, the process is very safe and effective, it just requires more skill, patience, and time.
The immediate healing process is very similar, regardless of the ink colour according to skincare experts at Illusion Laser Clinic. You can expect:
The main difference, according to skincare experts at Illusion Laser Clinic can be the intensity. Some clients report slightly more swelling or itchiness when treating red ink, likely due to the sensitivity factors mentioned earlier. However, the aftercare instructions by Illusion Laser Clinic practitioners, keeping the area clean, dry, and protected from the sun, are identical and crucial for all tattoo removal.
