Base color doesn't matter,,., if "unique" is important to you, you can overlay the whole drone (& remote!) with a custom skin sticker kit & have any color you want..
.. and then change those stickers every couple of weeks for an entirely new look each time
I would always select white if possible, for avoiding the additional heating up in summer time and bright sunlight, caused by darker colors.
It also makes finding the drone on ground, e.g. in gras much more easy.
I initially bought the Onyx Black. But realized it's too plain... hahaha. So I exchanged it for the Arctic White. And I am happy. But it's all personal preference.
I was quite indecisive about which color to pick as I thought they all have a unique appeal. So I went for the white, not too flashy, and not too invisible in case I lose it.
Note, only the red one has a glossy finish. The white and black ones are matte.
