“This publication accompanies the exhibition ‘Suprasensorial: Experiments in Light, Color, and Space,’ organized by Alma Ruiz and presented at The Museum of Contemporary Art, Los Angeles, The Geffen Contemporary at MOCA, 12 December 2010-27 February 2011” (via Supra sensorial : Experimentos en Luz Color, y Espacio = Experiments in Light, Color, and Space (Book, 2011) [WorldCat.org]).
The principle cataloguer in our department stopped by my desk to show me this today. The book has a red gel overlay for reading the green text (which is in Spanish) and green gel overlay for reading red text (which is in English). The green and red text are printed on top of each other, so you need the overlays to read it.
