Color-graphemic synesthesia is "a form of synesthesia in which an individual's perception of numbers and letters is associated with the experience of colors" (Wikipedia). I didn't know this is a real thing until I saw something about it online. It genuinely surprised me that not everyone sees numbers the same way I do.
I have always noticed that when I think of numbers (and a certain few letters) I link them to colors. 1 is a medium blue. 2 is green. 3 is yellow. 4 is orange. 5 is red. 6 is purple (the reason my favorite number is 6). 7 is golden-orange. 8 is indigo. 9 is indigo. 10 doesn't have a color to me. etc. In the second grade, my class was talking about "lucky numbers" and we all had to tell the class what our lucky number was. I wanted to say that 6 was my favorite number because it is a pretty color, but when none of the other students mentioned color, I hurriedly made up a reason and said that it is because my name has six letters. When I was little, it bothered me when numbers were colored the "wrong" way. If there were numbers or letters hanging on the wall in school that were colored the wrong way (unless they were all the same color) it would distract me and I couldn't focus on my work. When I was reading online, this picture upload.wikimedia.org/wikipedia… showed up and it bothered me so badly, because the colors and numbers don't match up for me, that I had to close it. xD
However, there are some benefits to this as well. Some people with this form of synesthesia are really good at memorizing music, long numbers, and doing complex arithmetic. I don't know about that. xD But it is more common in artists so maybe it helps with creativity. It helps a bit for me with my memory. For example, I remember that my friend Zac's favorite color is purple because Z is purple to me. But it also makes me mix up numbers in my head sometimes when there is an important date that I'm supposed to remember and the numbers are both either "warm" or "cool". For example, if a paper is due on November 4, I might think it is due on the 7th because the numbers are similar colors. I also sometimes mix up numbers in my head if they are shaped similarly (for example 3, 8, and 9 all have similar curves) but this has nothing to do with synesthesia. But, 8 and 9 are the same color to me so that makes it all the more confusing to my poor little mind. This is why I ALWAYS write down important dates.
Honestly, other than a few little annoying things, this doesn't cause any trouble in my life. And as I mentioned above, I don't even notice it usually because it is normal to me and I've always seen colors in numbers and some letters.
Does anyone else perceive things this way? Do you know someone who does? Have any funny moments that have to do with color-graphemic synesthesia (or any other form of synesthesia)? Let me know.
