Carolina Alexandra Falkholt, with the pseudonym Blue, born 4 March 1977 in Gothenburg, is a Swedish artist, graffiti writer and musician. Sometimes she uses her own coined term grafitta, to describe her art. It is a play with the two words graffiti and fitta, the latter means "pussy" in Swedish but also with a Swedish grammatical habit of setting a gender to work titles where an "a" denotes female role.
