Color can affect quality?

[OZDF]

Hi Everyone,
I have a question: during my works I noticed that some colours can affect quality of the final mesh. I am working on a wooden sculpture (not painted, so the color is the classic wood color), and the basement is a very colourful red.
Near the basement the mesh is really distorted and the shape of the basement is full of crazy bubbles.
I tried to desaturate the reds and I obtained a little better result, but not sharp as the rest of the sculpture. That's really strange because the source pictures are good and allow me to obtain good results on every other part.

The parts with lesser results probably have less overall noise and thus the reconstruction is not as accurate? Color per say should have no impact on any of it I think.
