The wheel spins very fast in front of the chip and fools the eye into thinking it's seeing a full-color image, when in fact it's seeing a series of red/green/blue images at a very high frequency. 1-chip DLPs are cheaper to produce, but there are image quality compromises due to the single chip design.
That would explain why a DLP image (on a home projector, at least the ones I've seen) appears to go monochromatic (either red, green or blue) whenever I blink.
