Every single Valentine’s day we have to argue over where to place boundaries when dividing a continuous spectrum into discrete sections, but human language adds boundaries progressively as time advances and violets are blue except in languages that have words for purple.
Roses aren’t red either, but red is such a linguistically ancient concept that it tends not to get divided up as quickly as other color concepts. The points at which red stops being red are much further from the center of red than the points at which blue stops being blue are from the center of blue. But excluding the violets that are white, we can say two things for certain:
- Violets are definitely blue.
- Violets are definitely not blue.
