Comment on that link,
It’s interesting, because I can find a lot of people claiming that puce green is a colour that exists, but I can’t find many usage examples
I’ve only ever known it to be purple, even in pre-web days.
EDIT: Wikipedia –
Puce is the French word for flea. The color is said to be the color of bloodstains on linen or bedsheets, even after being laundered—or from a flea’s droppings, or after a flea has been crushed.
The Oxford English Dictionary (OED) dates the first English use of “puce” as a color to 1778. The name comes from the French word puce, or flea
…
Puce green dates back to at least 1810, when green tea was described as “puce green” in color. This phrase is still found today in the UK and the US, where it means a “pea soup” color. Hypotheses that this usage comes from misappropriation or derivation from “puke green” or “pus green” are purely speculative.
So it’s purple according to the OED, can also be green but either way it’s not a US/UK thing. (Like in your link, my gran used to use it to describe someone red with anger.)
