Synesthesia is a cross-consciousness mechanism that usually refers to similar sensations that are evoked between stimuli of different senses. [Color-graphemic synesthesia], the authors write, appears to emerge in early school years, where first major pressures to use graphemes [symbols and codes such as letters and numbers] are encountered, and then becomes cemented in later years., In fact, they say, for certain abstract inducers, such as graphemes, it is implausible that humans are born with synesthetic associations to these stimuli.

Modern scientists have known about synesthesia since 1880, when Francis Galton, a cousin of Charles Darwin, published a paper in Nature on the phenomenon. For certain types of synesthesia, you can take the Synesthesia Battery, an online test, to help confirm. Thus, synesthetic color differences can facilitate performance on tasks in which real color differences facilitate performance for nonsynesthetes and can impair performance on tasks in which real color differences impair performance for nonsynesthetes.
