The colour of stanchion.

FODCADEMON

Something suddenly occurred to me the other day at a trail centre and it may well be an incredibly stupid and ignorant thing to ask, but does the colour of the stanchion affect a fork's performance or is it purely aesthetic? I understand that the colour itself would play any role in performance, but is it a sign of a different material or coating and what impact does this have, if any.
Please help,

Sometimes is aesthetic - some are specially coated to reduce friction.

Chrome is usually only applied to steel, which means the fork will be heavier.

Often aluminium stanchions are anodised. So they will be lighter than steel, and probably a bit slicker.
