Synesthesia is a condition in which one type of sensory stimulus evokes sensations associated with a different sense, as when hearing a sound stimulates the visualization of a color. Approximately 1 in 2,000 people have the condition, and most of those affected are female. Synesthesia can result in a number of cross-sensory experiences, but it most commonly manifests as a grapheme-color interchange. Which Russian painter, regarded by some as the originator of abstract art, had synesthesia? Discuss
