A:
It is really a matter of preference. The odd color vane/feather is simply a
visual point of reference for positioning your arrow correctly and
consistently on the rest. I generally shoot a compound bow with the "nock"
vane facing up whereas shooting my traditional the "nock"vane faces to the
left away from the site window (for right-handed shooters).
Notice when you nock an arrow with the colored vanes. The nock vane is
facing outward, the other two vanes are on the top and bottom. The bottom
vane is the only one making contact with the rest as the arrow is released.
If you were to place the colored vane to the inside facing the rest, the
vane would cause the arrow to kick out away from the bow as the arrow
passes the site window.
If you are shooting wood arrows and decide to you want fletching all of the
same color, you could build the arrows with nocks that have position
indicators on them. If you are using carbon, best bet is to look each time
to ensure your nock vane is facing outwards.
Hope this helps
