John Vitale (1979, Illinois, USA) is a self-taught abstract painter whose work delves into the complexities of the human experience. His paintings are charactarized by organic shapes, lines, plateaus, and rich color palettes, creating captivation visual narratives. Vitale employs a meticulous process, often spending weeks on a piece, where minor adjustments - such as a single mark of color shift - can bring a painting to its resolution. He utilizes a combination of acrylics, house paint, enamels, pencils, canvas scraps, and oil sticks, layering materials to archive time and experience tangibly.

Since the mid 1980s, Christiane Grimm has been creating color and light spaces, focusing her research on the luminosity of color, its nuances, combinations, and effects on viewers. A trained architect and self-taught artist, Grimm works with various materials, including oils, acrylics, pastels, perspex, antique glass and ribbed glass. She creates visual objects, architectural light sculptures, and boxes that explore how color perception is influences by lighting and material. Her works often feature milky ribbed glass that refracts light, producing a variety oh hues and a sensual effect resulting from the interplay between color, composition, space, material and lightning. Grimm's exploration extends to the phenomenon where a color's value is never absolute but varies in combination with other colors, highlighting the dynamic nature of color perception.
