All my life, I have associated letters, numbers, and even months with colours. For example, '6' is brown with a maroon hue and even has personality traits. It's an overweight person with a raspy voice.
I have always organised the alphabet in my mind with colours. Letters before 'O' have typically 'cooler' colours including blue, green, purple and maroon.it follows a pattern as well. The letter 'O' is white, and the letters after that go into warmer colours like red, orange, brown and yellow.
Each letter also has it's own colour
With months, November is pine green and September is a very stark red. Each month has a unique colour
Also, I have associated some certain types of pain with a certain colour, but this is not as strong as the other
