A study done by V.S. Ramachandran and E.M. Hubbard investigated several questions that many people had about grapheme. It showed that there were different factors that affected the color of the characters, such as: upper or lower casing, font, and “wrong” coloration. When the letters were lowercase they appeared less saturated or considered “shiny” or “patch” to the synesthete, with only a few exceptions. Regular serif fonts like Times New Roman, Arial, as well as a few odd fonts produce more vivid colors. Most interesting among the changes that were made to the characters were when the characters were given a color that did not coincide with the colors that the synesthetes were most commonly known to give to it. They used numbers and when the incorrect color was attached to the number it caused the synesthete to have difficulty recognizing the “correct” color as well as a visual discomfort (Ramachandran et
