I’m a migraineur and there’s an overlap between that group of people and those who are synesthetes. But it turns out that my kids, who do not (yet?) suffer from migraines, also associate colour strongly with things that other people do not usually associate colour.

For example, days of the week. We’ve hard arguments over what colour ‘Monday’ is, for example. So this xkcd cartoon made me laugh.
