Rupprecht Geiger's Bluish Red and Blue-Black (1961) is an early screenprint on cardboard. Catalogued as WVG 41, the artwork forms part of a closely related group of abstract prints in which Geiger examined chromatic inversion, reversing the interaction between red, blue, and black to test their visual intensity.

In this composition, a saturated bluish red field is set against a dense blue-black form, generating a concentrated dialogue between luminosity and depth. Created during a decisive phase in Geiger's early 1960s practice, the fine art print reflects his growing conviction that color itself could function as subject and structure. With reduced geometry and heightened contrast, the artwork underscores his systematic exploration of how tonal shifts alter spatial perception and emotional resonance.

Published in 1961 in a limited edition of 50 prints, Bluish Red and Blue-Black is hand-signed and numbered by the artist.
