Chartreuse. Avocado. Lichen. Are those green, or are they yellow? Everyone in this shop has an answer and not everyone has the same one, which is awkward, because a scarf has to be filed under one colour or the other before it can go on a reference sheet.
Below are all 132 dyes we have, laid out by hue. Pick a boundary, drag it to where you think it belongs, and watch the jars change sides. If you get one you feel strongly about, the address bar holds your answer — send it to somebody who disagrees.
The jars nearest the boundary, the same distance out in both directions — at least three a side, and further out when the catalogue is thin there. A ring means the jar changes section at the line you’ve set.
Every dye sorted into its section by the same three-axis rule. Hover a square for its name. Grey and black are working colours here — they ground the colours beside them — so a recipe only gets filed under one of them when it is the only thing there.
Nothing on this page writes anything, and neither does the classifier itself. It fills a form in and a person confirms it. That is deliberate: a wrong band is silent — you look in the orange section, the scarf isn’t there, and nothing tells you it was filed under red. Measured against the dyes actually in use, the hex path gets 85–90% right, which is nowhere near good enough to print unread.
There is no indigo section. The blues here run 219–248° and the violets 254–277°, so indigo has no territory of its own — the section would be empty or arbitrary, and worse, you’d never know whether to look there or in blue. Pink and brown are sections for the opposite reason: both are what someone actually says out loud about a scarf.
