  A {\em blink} is a plane graph with a bipartition (black, gray) of its edges.
Subtle classes of blinks are in 1-1 correspondence with closed, oriented and
connected 3-manifolds up to orientation preserving homeomorphisms
\cite{lins2013B}. Switching black and gray in a blink $B$, giving $-B$,
reverses the manifold orientation. The dual of the blink $B$ in the sphere
$\mathbb{S}^2$ is denoted by $B^ \star$. Blinks $B$ and $-B^\star$ induce the
same 3-manifold. The paper reinforces the Conjecture that if $B' \notin
\{B,-B^\star\}$, then the monochromatic 3-connected (mono3c) blinks $B$ and
$B'$ induce distinct 3-manifolds. Using homology of covers and length spectra,
we conclude the topological classification of 708 mono3c blinks that were
organized in equivalence classes by WRT-invariants in \cite{lins2007blink}. We
also present a reformulation of the combinatorial algorithm to obtain the
WRT-invariants of \cite{lins1995gca} using only the blink.
