"Name-color" synesthesia making consistency test

In this paper, we perform a consistency test for "name-color" synesthete. The test subject feels the color when he sees characters, humans, and objects so on. We perform a consistency test with him. We want to clarify what is the "color-name" synesthesia. We selected character-kanji which represents Japanese name. If the character-kanji of two or more characters, we could not measure the exact data to each characters will interfere. We resolved by the one-character-kanji. We could measure more accurate data to the mosaic background in order to avoid interference with the background color. We were able to prove that the subject has the consistency of the relationship of color and character. We will look at the brain waves in the future. There will be a need to see what is moving how in conjunction.
