In my personal opinion, graffiti is just art, not a design. Graffiti artist always want to express their feeling, their individual altitude to the public. The communication from the graffiti is not clear, it's abstract. The are not common rules for the graffiti, from the shape, colors, font, etc.
However, graffiti especially can extent the creativity and imagination of the artists, help them to increase the skills alot
Graffiti really has become an international style in terms of its representation more than its visual iconography is primarly western. Acording to the article about Japanese graffiti artist Gajin Fujita. This is some comments of his works:
"Imagine that Japanese film director Akira Kurosawa was an East L.A. graffiti artist and you’ll get an idea of what Fujita’s artworks look like. At once art-savvy and street-smart, his works don’t just sit politely on the wall; they burst across the field of view like a multicultural electric spectacle for the 21st century. His paintings deliberately dazzle the eye, setting forth sensuous layers of color and patterns atop shimmering gold leaf with bold graffiti-style lettering and dramatic, oftentimes lurid, narrative imagery. At once drawn from tradition and deeply irreverent, Fujita’s works are a wild blend of sources and ideas, of high art references and popular culture: what theorists might call post-modernist, curators might call multicultural, and what the artist himself sees as ‘sampling’—a form of visual hip-hop. But for all their eclecticism, Fujita’s works are very much a personal statement, a giddy but authentic expression of who he is and where he comes from as a Japanese-American who was raised in a largely Hispanic area of Boyle Heights, in the vast multicultural sprawl that is turn-of-the-millennium L.A. Unlike those L.A. artists who defensively reject any notion of being “regional,” Fujita embraces his identity as a Southern California artist. Indeed, he parades it confidently, like a graffiti tagger claiming his turf. “I feel proud that I’m from the West Coast of the U.S.,” he says. “I certainly grew up here, was raised here. I feel this is my stomping groups.”
