*Synesthesia is a neurological phenomenon in which stimulation of one sensory pathway leads to automatic, involuntary experiences in a second sense. For example, some see individual letters of the alphabet and numbers shaded or tinged with a color. Chromesthesia is the association of sound with colors. Others ascribe tactile sensations to numbers (i.e. 4 is scratchy).
