This color thesaurus post has been making the rounds for a while. I applaud the effort, but several of the colors seem wrong. The creator, Ingrid Sundberg, acknowledges that there’s no official color guide. But there is general consensus on many colors, yet this thesaurus diverges from the generally accepted nomenclature. 

Scarlet, for example, is very similar across many diverse sources. But this one seems a bit too dark. It’s easy to pick out other examples that also seem off.

I love the idea of accurately naming colors in writing, but I don’t think this is the best reference for doing so.
