Any two adjacent colors must either have the same name or different names.
- Filligree 7y agoThis assumes a color must have only one name. Why not two, or more?
- baddox 7y agoHaving more than one name doesn’t change the story, and neither does some colors having no name at all. For each pair of adjacent colors which is indistinguishable to most people, and the two colors must either have the same name (the two sets of names are equal) or different names (the two sets of names have no intersection).
