not directly unless you hack the display code.
But assuming you are on an ANSI capable terminal, you could replace
the matrix elements by strings, that represent colorized expressions.
Perhaps you can expand on the following idea:
bold(expr) := apply(concat, [ascii(27), "[01m", string(expr), ascii(27), "[m"]);
bold(x+y);
bold(0.0);
