Pastis – Jaune sur Bleu is a monumental oil on canvas by David Guez that commands attention through its saturated ultramarine field, rhythmically interrupted by assertive bands of yellow - a chromatic tension reminiscent of the bold simplicity found in Yves Klein’s monochromes and Barnett Newman’s \"zips.\" Guez builds a tactile surface with expressive brushwork, evoking both movement and silence, while the grid-like structuring of the yellow suggests an abstracted horizon or musical notation. With its evocative title nodding to the iconic French aperitif, this work merges sensory memory with formal abstraction, inviting viewers to navigate the boundary between color, perception, and cultural reference.
