“Medlite c6 tattoo removal - black lines turned red after treatment”

Seeking help:

About 6 weeks ago I got 2 one inch square test areas treated and have seen significant fading of the less dense black shading but strange results from the thin black lines. It seems the laser immediately turned the black lines bright red. There is no black ink left visible on the line and it seems the red color is not from irritation of the skin but from some kind of transformation of the ink. Is this possible? The bright red color faded slightly to faint red-orange in about 5 weeks. Has anyone else seen this before? Should we try treating the lines with the wavelength for red? Could it be possible that the tattoo artist mixed a brown or red color in the black ink he used to trace the design with a thin needle? Also, it looks like the blue color was achieved by mixing black and dark blue. Does anyone have any advice or experience in removing this type of pigment. What results can I expect? I appreciate any advice.
