  In this paper, we analyze a sample of clippings from paintings by the late
artist Bob Ross. Previous work focused on the qualitative themes of his
paintings (Hickey, 2014); here, we expand on that line of research by
considering the colorspace and luminosity values as our data. Our results
demonstrate the subtle aesthetics of the average Ross painting, the common
variation shared by his paintings, and the structure of the relationships
between each painting in our sample. We reveal, for the first time, renderings
of the average paintings and introduce "eigenross" components to identify and
evaluate shared variance. Additionally, all data and code are embedded in this
document to encourage future research, and, in the spirit of Bob Ross, to teach
others how to do so.
