Synesthesia is when two senses combine with each other and form relationships. For example, I have the most common kind: grapheme-color synesthesia. Mine looks like this. The only one that’s supposed to be black is “1”. Otherwise, the ones in black have no color associated with them.
I used to. I can’t remember the colours these days but as a kid they were really strong. Then over time it just faded.
The colours weren’t just associated with individual digits, weirdly. So 1 and 2 may have certain colours, yet 12 might be a completely different colour to either digit. I don’t remember words working this way though.
Yeah, some words and numbers do that to me, too, but I just ignore those. They don’t seem as special since there are only ten single digit numbers (including zero at least) and every other number combo is just 1/90 (or whatever the correct math is lol).
But the word “ice” for example, is why I colored the “i” in the picture cyan. But a standalone “I” as in “I went shopping” is yellow, like “c” or “p”. I have a bit of preference and have been trying to make my mind see every “i” as cyan because no other letter, number, day, or month is colored cyan. It would make that letter special. :) Also, in words like “picture” the “i” basically loses its color because “p” outshines it.
