When I was a child, I used to say red very strongly.
But as I got older it became purple. Not just any purple, so I will have to try and find an example.
When I was a child I had mild synesthesia (common in autistics) and the days of the week had a very strong colour association to me - almost to the point of saturating my vision with the colour. (I read recently that Daniel Tammet (autistic author) has a similar thing. I still remember the colours and the feeling vividly but don't actually feel it anymore.
