I don’t know what you’re on about. The article and its references did not provide a non-ambiguous definition. Instead, we have “highly absorptive colors”. I did not claim that Wikipedia was the arbiter of truth, but in the absence of any definition in the article it’s fair game. I am not going to go through a literature review for this, either. I already spent an order of magnitude more time to read that article’s references than you took to write… this.
