I am not a synaesthete and I wonder how other non-synaesthetes perceived the '5 vs 2' diagram. Even though I see all the digits in plain black, the triangle of 2s immediately stood out to me. The author writes:
'For me, four-leaf clovers are a different shape so they stand out in a clover patch very much like this. Unlike letters and numbers, however, I don't get a sense of color, it's more like a sense of movement.'
But even as a non-synesthete, I felt a sense of movement in the 2s, as if they were little swans swimming against the bevy of 5s. But I felt no such movement when looking at the photographs of clovers. I could only spot a few four-leaf clovers at a quick glance because the pale markings on them form a rough quadrilateral, so I was essentially spotting those shapes rather than the four leaflets themselves.
If this sort of topic interests you, I wrote an article earlier this year about number–colour–phoneme associations: https://susam.net/assoc.html
As I mentioned, I do not have synaesthesia, yet the associations between numbers, colours and phonemes are quite strong in my mind due to early exposure to CGA colours and mnemonic systems. For instance, I find it hard to think of the number 1 without thinking of blue or the phonemes /t/ and /d/, or to think of 4 without thinking of red or /r/. I have written more about it in the article linked above.
