Hearing colors in songs?

I know some people with autism hear/feel color when they listen to music, but I'm pretty sure I've heard of another specific disorder where someone can listen to a song and hear specific colors but I can't remember what it's called. I may just be imagining that this exists, but if anyone knows I would really like to know what this is and would be very appreciative of your help. Thanks in advance!

Sound 鈫?color synesthesia

wikipedia or google it. very interesting stuff.

This is the beginning of the wikipedia article:
Synesthesia (also spelled syn忙sthesia or synaesthesia, plural synesthesiae or synaesthesiae)鈥攆rom the Ancient Greek 蟽蠉谓 (syn), meaning "with," and 伪峒聪兾肝废兾瓜?(aisth膿sis), meaning "sensation"'鈥攊s a neurologically-based phenomenon in which stimulation of one sensory or cognitive pathway leads to automatic, involuntary experiences in a second sensory or cognitive pathway. In one common form of synesthesia, known as grapheme 鈫?color synesthesia, letters or numbers are perceived as inherently colored, while in ordinal linguistic personification, numbers, days of the week and months of the year evoke personalities. In spatial-sequence, or number form synesthesia, numbers, months of the year, and/or days of the week elicit precise locations in space (for example, 1980 may be "farther away" than 1990), or may have a (three-dimensional) view of a year as a map (clockwise or counterclockwise).


It discusses sound to color synesthesia as well:
In sound 鈫?color synesthesia, individuals experience colors in response to tones or other aspects of sounds. Simon Baron-Cohen and his colleagues break this type of synesthesia into two categories, which they call "narrow band" and "broad band" sound 鈫?color synesthesia. In narrow band sound 鈫?color synesthesia (often called music 鈫?color synesthesia), musical stimuli (e.g., timbre or key) will elicit specific color experiences, such that a particular note will always elicit red, or harps will always elicit the experience of seeing a golden color. In broadband sound 鈫?color synesthesia, on the other hand, a variety of environmental sounds, like an alarm clock or a door closing, may also elicit visual experiences.
