got itHe’s shooting RAW, not JPEG. So he is in control of colour in post, not the Picture Style. His complaint is he can’t make the colours in his converted CR3 files look like the results from the CR2 conversions he had with the 6D.You could use luts if you wanted to, but the easier and simpler thing to do is just use Canon's Picture Style Editor and swing the purple hues more over towards blues so that right out of the camera, the JPGs (and video) is more to your liking.I think the OP is simply unhappy with the colours he is getting. He is used to his 6D, which is entirely understandable. He finds the R6 in some undefined way different, and in his sight this means inferior. There are many ways to make them look similar if not identical, and there is no underlying reason for an objectively quantifiable “difference”, given a RAW workflow. Changing camera bodies is therefore unlikely to remedy his problem. Personally I have found little if any colour balance difference from the 5D classic/2/3/4 series and 6D2 right through to my R5 and R7. And I am very picky in regard to IQ and colour, for which I have a calibrated monitor and a fully calibrated printing workflow.I dint have R6 or R8, but i own R6II currently.
Compare to my 1DX II , i found R6II jpeg image has improve DR , better tone gradation , less blown highlight and better shadow detail.
Another different ( improvement on R6II ) are skin tone colour, especially people shot which has different skin tone in same frame. Compare to 1DX II ,no more weird tonal and deeper shadow thing happened on darker skin person.
Both shot JPEG In stadard picture style, R6II has more close to scene colour . Much better/accurate AWB performance on R6II too.
I've owned 5d, 6d, RP, R8, etc, etc
I can get about any colors I want using dxo PL and adjusting the settings
