Walker Winn's attachment to color began in childhood. As an identical twin, he and his brother Taylor, also an artist, had identifying colors in the early days - Walker (blue), Taylor (red). Beginning life with a personal ID color launched an ongoing interest in the role color plays in personal, cultural and historical contexts.

Since 2005, Winn's geometric abstractions have revealed a distinct progression of forms, colors and materials. Early small oil works include the floating monochromatic trapezoids of the Cubist Series (2005-2006); the stacked, shaded, round-edged polyhedrons of the Squares Series (2006-2011); and flowing, small-celled, frosted color grids of the Panels Series (2007-2014).

In his current Fields Series (2015 to present) the artist explores optical and emotional effects of color relationships in ordered grids of hard-edge, solid pigment square sequences on large, stained, square-format wood panels. Each series echoes Winn's early interests in the colorful geometry of origami and manipulation of materials for enhancing the effects of color.

Most recently Walker Winn was selected by the City of Austin to exhibit his works through 2018 in the People's Gallery of the Austin City Hall complex. He also was named a finalist for the 2016 Austin Art Boards public arts billboard project. For three consecutive years (2005 - 2007) Winn was selected for the Ahead of Their Time exhibition at the Austin Contemporary at the Jones Center. In 2006, he was the youngest artist to be selected as a City of Austin People's Gallery artist. In 2007, Winn was commissioned by Gibson Guitar Corp. as a showcase guitar artist in the Austin GuitarTown public arts project with the City of Austin. He has shown his work in regional and national venues since 2004.
