My wife has synesthesia, the audio/visual kind. It affects her life a lot with pros and cons because sometimes a bright light can be excruciatingly loud or her vision gets blocked by watercolor-like colors from hearing a loud noise or from someone talking. She also has her own amazing ways of understanding math, music, linguistics. We have a friend who has the taste/touch kind, he doesn’t like slicing tomatoes because of the taste he experiences from the feel of them, so he wears gloves while slicing tomatoes.
Always interesting to learn more about synesthesia and find out about other people’s experiences of it. Looking forward to sharing the work of the artists mentioned here with my wife. Thanks for this thread!
