  We present narrow-band images of the Red Rectangle (RR) nebula which reveal
the distinct morphologies of this intriguing nebula in different optical
emission bands. The morphology of the RR nebula in blue luminescence (BL) and
extended red emission (ERE) are almost mutually exclusive. We also present the
optical detection of the circum-binary disk of the RR in the light of the BL.
The total intensities from the two optical band emissions (BL and ERE) when
summed over the nebula are of comparable magnitude. Their spatial distributions
with respect to the embedded illumination sources lead us to suggest that they
may be attributed to different ionization stages of the same family of
carriers.
