Even if we are not synesthete nor have perfect pitch, it is possible to learn (for a while, for a long time actually) to be synesthete: obvious example: the alphabet. If I see an A, I have trouble not thinking about the sound "A".  It is even possible to prove that the same way we prove syntesthetes have trouble sometimes because of the interference of symbols, for instance by writing BLUE in red - it takes more time to read it. Now, come the interesting idea: why do we use only black and white and SHAPES to create this sound-to-shape synesthesia? Because it is obvious that producing different colors was more difficult than creating different shapes; but now, we could easily control, say, an RGB light by, say, waving a magic stick like the sony controller in the air and exploring the RGB or VHS space.  Then, the question is: could we create a solid color-to-sound synesthesia, and more particularly, a colour to LETTER or syllabe synesthesia? that would mean we could
