Karen Rips has posted about Richard Diebenkorn, who I must admit I'd not heard of before, her full post is here but what really caught my eye was a quote from a book about his years in new Mexico -
"He described three ways that lines can be used, implying that
successful abstractions employ all three. Lines form the outlines of
shapes; lines move independently of color fields or shapes; and lines
exist behind or within color fields."
An interesting idea to explore .......
