Well... I went to SGH with the intention of picking up a pair of Jupiter Factory lights, however, I couldn't decide which one to get, the brushed w/ice polarized or Black w/blk iridium polarized so I got both.
its just a characteristic of anodizing aluminium. slight variances in the metal result in slight changes of the color. it would actually be impossible for them to be separate pieces and the exact same color.
and i only used it cuz i like showing off and it just happens to match perfect. i'll see if i can get a better pic. the dark blue JFL is such a great color.
