Veils: When an initiate creates a warding, she can choose
and imbue the warding with any one veil she knows how to
create. These veils duplicate the layers of a prismatic wall and
are described below. An initiate’s caster level for these veils
is equal to her arcane spellcaster level.
You get the effect that the prismatic wall produces. If something diverges in the iot7v text, you get prismatic wall effect and whatever iot7v provides, unless a specific exemption is listed. Red and orange don't list what they don't do to arrows, so they do... do what they do.
Anyways, you're seriously overthinking things. Stop by a convenience store and buy some banana red mad dog 20/20 for your next dnd session. If that doesn't work hit up the liquor store and don't leave without something orange. Self medicate, and the problem will solve itself.
