  We present first results from a targeted search for brown dwarfs with unusual
red colors indicative of peculiar atmospheric characteristics. These include
objects with low surface gravities or with unusual dust content or cloud
properties. From a positional cross-match of SDSS, 2MASS and WISE, we have
identified 40 candidate peculiar early L to early T dwarfs that are either new
objects or have not been identified as peculiar through prior spectroscopy.
Using low resolution spectra, we confirm that 10 of the candidates are either
peculiar or potential L/T binaries. With a J-Ks color of 2.62 +/- 0.15 mag, one
of the new objects --- the L7 dwarf 2MASS J11193254-1137466 --- is among the
reddest field dwarfs currently known. Its proper motion and photometric
parallax indicate that it is a possible member of the TW Hydrae moving group.
If confirmed, it would its lowest-mass (5--6 MJup) free-floating member. We
also report a new T dwarf, 2MASS J22153705+2110554, that was previously
overlooked in the SDSS footprint. These new discoveries demonstrate that
despite the considerable scrutiny already devoted to the SDSS and 2MASS
surveys, our exploration of these data sets is not yet complete.
