Hi, these warnings are generated by lcms2 without any active influence of darktable. Anyhow, I think this is a consequence of the Lab color space where most of the modules act in. Suppose a dark pixel with an Lab value of [1.0, 0.0, -5.0]. That's a fully valid Lab color - a very dark blue close to black. However this can not be represented in an RGB gamut. The closer you move to black in RGB the less you can represent colors, opposite to Lab. And I think that is what we are warned about by lcms2.
