Relative colorimetric vs perceptual

Relative colorimetric changes all the colours out of gamut to the nearest colour in gamut, so many colours change to the same one. It DOES NOT change colours in gamut.

Perceptual changes ALL the colours in the image in a proportional way so that they lie in the printer gamut. This happens also if the image does not contain out-of-gamut colours.

So if your image does not contain out-of-gamut colours relative colorimetric does not change colours, while perceptual changes them.

If your image contains out of gamut colours relative colorimetric can cause strange colour changes (only for the out of gamut ones), while perceptual does not cause such strange changes.

The speaker talks about skin tones (they are in the printer gamut, I believe): with relative colorimetric they do not change, with perceptual they change and this can be a problem.

IIRIC the speaker also says the the best thing is to make some tests, anyway.
