Yeah in speed colors not so important but if you really care then you need to know the look of the fields/bunkers you will play most often in. If woods and you want to be hidden the white might be rough. Also it will get filthy especially after some paint sprays on it and everything starts sticking.
On the flip it looks pretty when clean tho so I totally get why you would ask
Saw some picks of a Lv1 reverse stormtrooper gun... wooooo the white and black looks sick.
