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.
Ah, yep! Forgot to mention those. Months, as well for me.
Monday is blue like the letter M and is feminine, and motherly. Tuesday is bright yellow, masculine, and kind of young. Wednesday is dark green and is a tomboy, no idea about age. Thursday is yellow-orange, masculine, and fatherly. Friday is bright orange, masculine, and young. Saturday, dark purple and an old grandma. Sunday is baby pink, gender neutral and 20ish years old.
January is a blueish purple, cold (obviously), is feminine, and tastes like grape. February is an orangeish pink, feminine again, and tastes like citrus. March is blue and masculine, and smells like leaves. April is red and yellow, feminine and has a flowery scent. May is blue and feminine, kind of shy. June is dark purple and orange, feminine, and quite lively. July is dark purple and pink and is like the twin to June, but toned down a bit. August is rust colored, masculine, old, and a bit mean. September is magenta, masculine, young, and rebellious. October is vivid orange (didn’t see that coming, did ya? lol), gender neutral, and fun-loving. November is the color of a schoolbus, and is masculine. It’s basically Thursday, but in month form. December is light pale blue, cold, masculine, and has a gentle authoritative air about him.
There’s an experiment you can give yourself at home to get a sense of what’s a normal association for sounds and shapes. For example, you have an oval and an 8 pointed star shape. One is named Kiki and the other Bob. Which is which?
It’s definitely Bob the oval and Kiki the star shape
