The new Black hair is all over the place with dreads / curls, often ends up as a light grey

Yeah in the bug report people are posting images of it across a wide range of hairstyles.

Yesterday when I first saw it, it was just dreads and curls that I had tried and I didn't want to overstate the case if I was wrong. But this one looks to be very widespread.

Some hairs with the new color are genuinely dark black, while the old 'black' is actually a dark black with blue highlights.

But most of them appear to have ended up as some random shade of gray. Some like the one just above being so light of a gray they look like one of the grays from the other side of the color choices...
