We define specific multiplicities on the braid arrangement
by using edge-bicolored graphs. To consider their freeness,
we introduce the notion of bicolor-eliminable graphs
as a generalization of Stanley's
classification theory of free graphic arrangements by chordal graphs.
This generalization gives us a complete classification of the free
multiplicities defined above. As an application,
we prove one direction of a conjecture of
Athanasiadis on the characterization of
the freeness of
the deformation of the braid arrangement in terms of
directed graphs.
