Abstract
Four primary colors may be used to render anaglyphs with wide color gamuts. The first image of a stereoscopic pair may be rendered in three primary colors while the second image of a stereoscopic pair may be rendered in a fourth primary color. Retinal rivalry may be avoided in an anaglyph by balancing the brightness contrasts of the first and second images for like subject matter. The retinal rivalry may be measured and controlled in anaglyphs by selecting values of a retinal rivalry color coordinate.
