(FUV−NUV) GALEX colours as a function of emission redshift for the 50 quasars observed with GALEX grism spectrograph by Songaila & Cowie (2010). One lower limit colour (source GALEX 1712+6007) is indicated with a red triangle. All nine quasars circled in green colour (including the lower limit) have spectroscopically identified LLSs. Their LLS redshifts are all at z <  0.95 within the FUV band, except z = 1.11 for the reddest object GALEX1418+5223 which does not appear as a FUV dropout.
