I noticed that fine color gradients in certain color tones render very poorly when using the new "Adobe Color" profile.
I'm using "Camera Neutral" as the default for my D800 files and the screenshot below shows the two side by side in a 100% crop (same photo, area of a purple flower petal, original on the left with "Camera Neutral", virtual copy on the right with "Adobe Color").
This is right after importing the photos, no edits at all, with my develop defaults of Contrast -33 and Blacks +25. Everything else is zeroed.

The purple blotches in the right image are way out of gamut of your monitor (the green channel is zero in the blotches). You're probably seeing the clipping of the image to your monitor.

What are you suggesting?

The blotches might not be the profile but the color simply being out of gamut on your monitor.

Hmmm. I'm not convinced. These blotches do not even disappear when I set contrast to -100 with the Adobe Color profile. By comparison, I can push the contrast quite a bit with Camera Neutral and the colors are richer then without the blotches.

If camera neutral works better for you than continue using it. Just because Adobe Color has been introduced doesn't mean that it's right for everyone in every situation. That's why there are still multiple profile choices.

Jim, the issue is of course that this is now the default profile. If there is a major rendering issue with deeply saturated colors it will impact a lot of people

Yes, but defaults can be changed. I suppose that didn't impact me because I had already changed the default for my camera anyway.

In the screenshot they are out of gamut. I am hovering the dropper over one of the purple blotches here and green is showing as zero.
You could check if this is the problem with the monitor gamut warning turned on in Develop in soft proof and soft proofing to a profile wider than your display. It's certainly possible that the Adobe Color profile has issues. I default to Camera Standard or Adobe Standard on my Nikons so I haven't really tried it much with my images.

My monitor definitely doesn't do AdobeRGB so I used that but the soft proof only shows a very small amount of pixels being out of gamut, so I don't think that's really it.

Really? The screenshot above shows areas out of monitor gamut. Here is the green channel of your screenshot. All the solid black areas are out of monitor gamut. It corresponds directly to the areas that look bad in your image above.

Clearly, I don't know enough about this. I'll send you the raw file if you don't mind, then you can take a look and play with it a little bit.
