  Using $N_c=3$ value of the parameter $a_2=0.09$ but including a modest
nonfactorized amplitude, we show that it is possible to understand all data,
including polarization, for color-suppressed $B\to\psi(\psi(2S))+K(K^*) $
decays in all commonly used models of form factors. We show that for $B\to\psi
+K$ decay one can define an effective $ a_2$, which is process-dependent and,
in general, complex; but it is not possible to define an effective $a_2$ for
$B\to\psi +K^* $ decay. We also explain why nonfactorized amplitudes do not
play a significant role in color-favored B decays.
