  If electroweak dynamical symmetry breaking is due to a chiral condensate of
color sextet quarks, dynamics analagous to ``walking technicolor'' will enhance
the condensate by orders of magnitude compared to the electroweak chiral scale.
This enhancement compensates for the exponential suppression of electroweak
scale color instanton interactions. As a result the $\eta_6$ axion can
naturally aquire an electroweak scale mass.
