If your tattoo has red, green, or bright blue ink and a clinic only has a single-wavelength Nd:YAG laser, it cannot fully remove your tattoo. This is a common honesty gap in Lima tattoo-removal clinics. Picosecond systems with multiple wavelengths (typically 532, 755, and 1064 nm) clear every standard ink color.
Why ink color matters
Different ink colors absorb different laser wavelengths. Black absorbs across the spectrum (easy to treat). Red and orange absorb 532 nm (green light). Green and blue absorb 755 nm or 694 nm. White, yellow, and skin-tone tattoo cover-ups are the hardest of all.
Wavelength absorption is fundamental physics — wrong wavelength = no effect.
Wavelength compatibility
| Ink color | Effective wavelength | Available in Nd:YAG single-wavelength |
|---|---|---|
| Black | 1064 nm | Yes |
| Dark blue | 1064 nm | Yes |
| Red | 532 nm | Sometimes (KTP add-on) |
| Green | 755 nm | No (alexandrite needed) |
| Bright blue | 755 nm | No |
| Yellow | 532 nm | Sometimes |
What modern picosecond machines offer
Most picosecond platforms offer 532 nm + 755 nm + 1064 nm in a single device. The same machine handles every standard ink color. Multi-wavelength = full color clearance.
Wavelength selection during treatment determines color targeting.
Particularly difficult cases
- White ink: can paradoxically darken with laser due to titanium dioxide oxidation. Typically requires test patch first
- Skin-tone cover-ups: same titanium dioxide darkening risk
- UV-reactive inks: rare, often unresponsive to all lasers
- Layered cover-ups: more total ink to clear, more sessions
- Pearlescent inks: may behave unexpectedly
What Elyzea uses
Picosecond platform with multiple wavelengths. Per-session: S/100 (~US$29). Color clearance is treated like any other tattoo — same machine, multiple wavelengths used in the same session.
Realistic expectations on color
95–100 % clearance achievable on most colors with picosecond. White ink and skin-tone cover-ups remain the hardest cases — discussed in consultation. Expect more sessions than for pure black tattoos.
Color-specific session counts
Multi-color tattoo session range:
- Black + small color accents: 5-7 sessions
- Multi-color professional: 7-10 sessions
- Heavily colored sleeve: 10-15 sessions
- Cover-up with multiple ink layers: 12-18 sessions
All shorter with picosecond than Nd:YAG.
Wavelength-by-wavelength approach
Single session may use multiple wavelengths sequentially. Typical full-tattoo session covers all colors in one visit.
Frequently asked questions
Can red ink be fully removed?
With picosecond and 532 nm: yes.
What about green ink?
Picosecond at 755 nm clears green. Nd:YAG single-wavelength cannot.
Will white ink darken with treatment?
Possible. Test patch essential.
How long for multi-color clearance?
7-10 sessions typical at picosecond. Each color may respond differently.
Can I treat colors separately or all together?
Same session uses multiple wavelengths.
What about gradient/shaded tattoos?
Most respond well. Some pigmentation gradients may persist.
Can I do partial removal of color only?
Yes. Discuss with consultation.
Bottom line
Picosecond + multi-wavelength = the only reliable colored-tattoo removal in 2026. Single-wavelength lasers cannot clear all colors. Lima at ~US$29 per session vs US $200-$600.
