This is what my alphabet looks like :).
I first read about synesthesia in my 10th grade Science Research class and studied it for 3 years. I never knew there was a name for this – I thought everyone experienced it. Certain school subjects tend to emote colors for me as well – math is red, history is blueblueblue, science is green. Darker colored letters are hard for me to pin down. First letters of a word are black. Double letters in a word are black. Numbers are combos of whatever color the individual numbers are.
