Ahh with colors this is a very wide topic to talk about. Also pardon my grammar.

For many people colors can mean so many things, and not every one can agree on what one color means to any one person. Some enjoy brighter colors, some enjoy darker colors. I enjoy darker colors, it makes me feel calm and safe, then again I enjoy darkness and cold more than bright and warm. Also a combo of colors can mean different things to different people.

Also look up the guy who has this device attached to his brain, I can not remember if it is when he hears something it makes a color, or a color that he sees is paired with sounds...it has been a long time since I looked it up.
