Having known perhaps less than 20 colours for my whole life, this collection is eye popping. And the design of website is perfect too
"chartreuse", "puce", "plum", " Burnt umber"
Which was also a light blue. Possibly light purple. Ish.
Where do they come up with these names?
The Marketing Department. Any resemblance to reality is purely coincidental.
I could have included "cherry blossom" in the list of English colour terms (In Japanese: Sakura) but a quick google shown that it refers to a range of related shades in English.
Evidence: any English dictionary.
