It's true that the \[ \] markers add the information needed to properly calculate the width of the prompt, and they have to be added directly to PS1, a function returning them doesn't work. But that is because bash coverts the \[ \] markers in PS1 to \001 \002, which is what readline ultimately needs in order to calculate the width. We don't need bash to do this conversion, we can use \001 \002 ourselves, and then the prompt command mode is not necessary to display colors. This is what functions returning colors are supposed to do [1].
