A stereoscopic digital projection system that projects stereoscopic images including first-eye images and second-eye images onto a display surface. The first-eye images are formed using red, green and blue first-eye light emitters having corresponding spectral bands with red, green and blue first-eye central wavelengths, λR1, λG1 and λB1. The second-eye images are formed using red, green and blue second-eye light emitters having corresponding spectral bands with red, green and blue second-eye central wavelengths, λR2, λG2 and λB2. The central wavelengths are arranged such that λB1
