I have never been diagnosed with synesthesia. I just want to put that out there.
I do, however, think that there is a blending of the sensory systems. It only makes sense – they are all being processed in the same organ with the same backbone of memory and experience and worldview and bias. Just because the input is from one type of sensory neuron doesn’t mean that the other senses don’t have an interpretation of said input.
Some of my observations:
Deeper sounds are wet.
Deeper sounds are cooler colors, but mostly blue or purple.
High pitches are sharp like a needle.
High pitches burn.
High pitches are bright yellow or white.
Fragrances that have a strong base in flowers are pastel-ish yellows and greens.
Fragrances that have a strong base in earthy, musky tones are deep blue or deep green.
English or writing is blue.
Math or chemistry is red.
Physics is black.
The number 4 is green.
The number 3 is red.
The number 1 is black.
The number 5 is dark blue.
Now, this may very well be a “yeah, everyone knows that” thing, but i don’t know that everyone knows that, and i’ve never really had an in-depth conversation about the color of sound.
I know that wavelengths probably have a lot to do with this, but i do not feel like researching that right now, but it will be the topic of an upcoming rabbit hole, I’m sure. I am curious if this is a “yeah, everyone knows that” type of thing though. If so, cool – but why don’t people talk about it? And if it is ubiquitous, why?
Just some randomness for your Sunday.
