I tried puce, mauve, aqua and got nothing for them.
Typed azure, got no result either.
Added.
I've never heard that word before in my life. Will add!
You could try to automate, get some images from a search engine for given phrase and try to average the color.
I would probably do an average and then for each image cut off say 20% colors that are most away from the average, and then average that.
That's a cool idea, though I don't know any search engine APIs that don't have a ton of restrictions on them. Google used to have a wonderful image search API, but it's either deprecated/discontinued by now.
