Why this galaxy is so blue? hes come up to earth diretion?

Due to the low z-band (red) images, it relies on a different color than the actual images. from the Bok telescope used for the BASS survey.

It is more red in DR6 and redder in SDSS.

In the north (above Dec=+32 degrees), we used the Mosaic3 camera for the z band (red), and there are some image-processing problems so that we over-subtract the light around bright galaxies, so they often come out looking blue-green like this.
