Field sequential projection displays exhibit a phenomenon of color breakup (Rainbow effect). This is considered to be a disturbing artifact with negative marketing impact. We describe the results of a psychophysical experiment comparing the visibility of the phenomenon in RGB and multi‐primary displays. Surprisingly, it is found that color breakup in color sequential projection displays with five primaries is equally (for 75 Hz) or less (for 105 Hz) visible than in similar displays with three primaries (at 180 Hz), despite the lower refresh rates.
