SynMap is an online tool for grapheme-color synaesthetes or anyone interested in grapheme-colour pairings in the general population.
When some people look at a grapheme (letters or nubers) they have an automatic colour experience linked to it. Their exact colour experience varies quite a lot, however this isn't as rare as many people think. About 1% of the population has grapheme-colour synaesthesia. SynMap is an online tool for recording the colours people have for different graphemes.
Below is the link to the SynMap for both synaesthetes who are interested in seeing their colours. It can also be used by researchers, for more details on research use please contact Árni Gunnar Ásgeorsson email@example.com.
