How to draw multiple commutative diagram like this one?

I want to draw a multiple ‘commutative’ diagram that looks as follows:

My working trial is as follows:

documentclass{article}
usepackage{tikz}
usetikzlibrary{matrix}
begin{document}
begin{tikzpicture}
  matrix (m) [matrix of math nodes, row sep=3em,
    column sep=3em]{
            & MC_1  &       & TM_1\
    MC_2    &       & TM_2  & \
            & BM_1  &       & TM_2 \
    BM_2    &       & FM_2  & \};
  path[-stealth]
    (m-1-2) edge (m-1-4) edge (m-2-1) edge (m-3-2)
    (m-1-4) edge (m-3-4) edge (m-2-3)
    (m-2-1) edge [-,line width=6pt,draw=white] (m-2-3)
            edge (m-2-3) edge (m-4-1)
    (m-3-2) edge  (m-3-4)
            edge  (m-4-1)
    (m-4-1) edge (m-4-3)
    (m-3-4) edge (m-4-3)
    (m-2-3) edge [-,line width=6pt,draw=white] (m-4-3)
            edge (m-4-3);
end{tikzpicture}
end{document}

that produces:

I need the arrow to be in blue color and the line in black. How to achieve this? Please help.

documentclass{article}
usepackage{amsmath,tikz-cd}

begin{document}

end{tikzcd}
]
