Chromosphere: The Color Theory Podcast
Ed Charbonneau
This podcast centers on my research and understanding of color, color usage, and optics as they relate to theories of human color perception in the making of visual art and design. By Ed Charbonneau, an artist (drawing & painting focus), and an adjunct faculty member in the Foundation, Fine Arts, and Creative Entrepreneurship Departments at the Minneapolis College of Art and Design, in Minneapolis, Minnesota, USA.

Focal Points and the Roots of Abstraction, part 1
Part one of a reading of an essay I am writing, Focal Points and the Roots of Abstraction.Human color vision adapts to the changing environment in many ways. Pupils dilate and constrict in order to regulate the amount of light entering the eye. The lens either bunches up or flattens out to change its shape while focusing light wavelengths along the spectral band at different proximities to the retina. Cone cells, and other light sensitive cells, perform plus-or-minus gains in activity to achieve what is known as color constancy, allowing humans to maintain a persistent perception of colors within changing light sources. Adaptations such as these take place at different rates of time, some more quickly than others; some more involuntarily than others, which may relate to how focal points form and dissipate within a visual field. This essay explores how adaptations of the visual system may generate focal points, and how representing light as colors informed the roots of abstraction.Send us Fan MailSupport the show

Harmony part 3: A New Canon
Part 3 of 3: The final installment, A New Canon, places the work of color theorists, Mary Gartside and Emily Noyes Vanderpoel in historical context so as to examine how their inclusion (and by extension, additional underrepresented color theorists and practitioners) may help us to understand how we may expand our contemporary approaches to color usage in all creative visual fields.

Harmony part 2
Part 2 of 3. In this episode, I read the middle portion of an essay I have written, which could become a chapter in a future publication. (Read in three parts.)Abstract:This essay charts how the term harmony came to be used by European and North American artists, designers, and educators as a qualitative descriptor of color usage and design. Originating in metaphysics and philosophy in BCE Greece as a method to link the functioning of the five senses, including color vision, the concept entered into the vernacular of design via architecture during the Italian Renaissance. Throughout the 19th and early 20th Centuries, theorists and educators claimed the authority to define objective harmonies in color usage and design; forming methodologies that have been ubiquitous in practice over the past 100 years. The final section of the essay, A New Canon, places the work of color theorists, Mary Gartside and Emily Noyes Vanderpoel in historical context so as to examine how their inclusion (and by extension, additional underrepresented color theorists and practitioners) may help us to understand how we may expand our contemporary approaches to color usage in all creative visual fields.
