We use optical photometry in three filters (r', i' and Halpha to create (r'-i', r'-Halpha) colour-colour diagrams of point sources in the Galactic Bulge Survey Fields (Jonker et al., 2011, Cat. J/ApJS/194/18; 2014, Cat. J/ApJS/210/18; Wevers et al. 2016, Cat. J/MNRAS/458/4530). We identify 1337 emission line candidates, 336 absorption line candidates, and 389 blue outliers in the catalogue. These samples likely contain a plethora of sources, ranging from chromospherically active stars, subluminous hot dwarfs, white dwarfs, CVs, planetary nebulae, LMXBs and variable stars to background AGN.
