  It is shown that a technicolor theory containing a color-octet technipion,
usually denoted by $P^{0'}_{8}$, will give rise to an enhancement of $t \bar t$
production at the Tevatron, LHC and SSC, via the process $gg \rightarrow
P^{0'}_{8} \rightarrow t \bar t$. The relevant cross-sections are computed
taking into account the large lower bound on the top mass coming from the "top
search" experiments at LEP and CDF.
  At the LHC and SSC, the signal is found to be comparable to the QCD
background, making the process quite accesible.
