  We present optical broad band B-I colour maps of a further sample of 10
Seyfert 2 galaxies. In these bands, the contribution from emission lines to the
total flux is small, and hence the images predominantly trace the continuum
distribution. As in our earlier colour maps of a sample of Seyferts type 1 and
2, we detect extended blue continuum components in the circumnuclear region of
several galaxies. These components are either elongated (in Mkn 533, Mkn 607,
Mkn 1066, NGC 5347, NGC 5953 and NGC 7319) or form a double structure across
the nucleus (in NGC 5929). They are closely aligned with the radio and emission
line axes of these galaxies and probably arise from scattering of nuclear
continuum light by extranuclear mirrors. Similar blue elongations (in Mkn 1 and
NGC 7212) and double structures (in NGC 788) are less well aligned with the
radio and line emission, and their relationship with scattering regions must be
considered uncertain. The colours of the blue maxima are consistent with those
expected from scattering off dust or electrons, a conclusion strengthened by
the combined sample of the two papers in this series. Our findings thus
strongly support the current unified models of AGN.
