I have several other types of syn, but I have noticed that when I hear sound it has a color. I do not actually see it like with my taste>color but it is constant. Most people's voices are beige or gray, but music is all sorts of colors. Am I going crazy or is this syn?
Yes, this is a type of synesthesia. A person’s syn falls into one of two categories; Associator or Projector.
A projected synesthetic reaction is when the synnie actually sees/hears/etc the reaction. This would be your taste>color.
An associative synesthectic reaction is when a synesthectic response is just in their mind space. This would be your sound>color.
There are lots of resources on this and if you would like to know more we would be happy to recommend some.
