@yours_truly the black pixels simply indicate the most rare combinations. It's a little misleading because the scale goes something like 90th through 97th percentile: dark orange, 98th percentile: grey, 99th percentile: black. So while a bright yellow or white pixel next to an orange pixel carries meaning - here's a unique value that holds some significance to humans - a black pixel next to an orange pixel isn't very meaningful. It's usually just going to be the statistically rarest value along rare values, like a min/max function.

@yours_truly Now, if you can find a black inside an island of white/yellow pixels, THAT would be interesting. It would probably correlate to values tied to superstitions.
And upon consideration, I wouldn't be surprised if there are at least a few black pixels of that nature
