I want to know , because it's very important for me .
Light colors, such as yellow, light green and turquoise are usually difficult to remove. Also, white, and any color that might contain white (such as pink) may darken, rather than lighten, with treatment.
In order to successfully remove a multicolor tattoo you require multiple lasers. There is no one laser wavelength that can cover all inks. In my practice I use up to 5 ! We must consider what wavelength your ink is absorbing and pair it to what laser you are using Black responds best because it absorbs all wavelengths but its favorite are YAG and RUBYRed responds only to one the KTP ( 532)Blue responds best the the Ruby followed by the YAG followed by the AlexandriteGreen responds best to Alexandrite and Ruby as a close secondYellow is hard reflecting most lasers but the 532 seems to be the best of what we can offer but still yellow may not respond.White reflects all so I never tell my patients white will come out. Sometimes it does but thats just luck.So all in all black with red tattoo higher up pn the body is your best bet if you think one day you may want it removed.
