Color‐color diagram of every star in SDSS with ﹩g^{\prime }< 21﹩ and within 9﹩\arcmin﹩ of Leo A (centered at ﹩9^{\mathrm{h}\,}59^{\mathrm{m}\,}23.92^{\mathrm{s}\,},+30^{\circ }44^{\prime }47.69^{\prime \prime }﹩ [J2000.0]). We target the 12 blue plume candidates with ﹩( g^{\prime }-r^{\prime }) _{0}< 0﹩. We identify 10 B supergiants (squares) and two H II regions (triangles).
