defColor                                       (Assignable)

        Contains an array of two numeric values used as indexes into the
        color table in the TBrowse object.  The first value determines the
        unselected color which displays headings, footings, etc.  It also
        displays data values when the browse cursor is not on the data value
        being displayed.  The second value determines the selected color.
        The selected color displays the current browse cell.

        The default value for TBColumn:defColor is {1, 2}.  This causes the
        first two colors in the TBrowse color table to be used for unselected
        and selected, respectively.  Note that colors set using
        TBColumn:colorBlock override those set by TBColumn:defColor.
