You may not have noticed them all, but autistic artist Jessica Park reports that this painting uses seven shades of black, nine shades of green, and five shades of violet, among other colors; the shades are applied according to "a diagram that she holds in her mind from the beginning."
Park is one of many autistic people translating their particular views of the world into art pieces. The work can be a comfort and relief to people longing to express themselves, and can also help others understand the mental processes of autism. A new book of art compiled by Jill Mullin, Drawing Autism from Mark Batty Publisher, rounds up many remarkable examples of work by people from all across the autism spectrum.
