  "Face for column display of entry properties.
This is actually only part of the face definition for the text in column view.
The following faces apply, with this priority.

1. The color of the reference face.  This is normally the level fact that
   is used in the outline.  In agenda-mode, it will be the face of the
   first character in the line.  The color is explicitly retained to
   make sure that the column line still looks a bit like the structure
   line it is masking.

2. The `org-column' face.

3. The remaining properties of the reference face.

Since column view works by putting overlays with a display property
over individual characters in the buffer, the face of the underlining
character (this might for example be the a TODO keyword) might still
shine through in some properties.  So when your column view looks
funny, with \"random\" colors, weight, strike-through, try to explicitly
set the properties in the `org-column' face.  For example, set
:underline to nil, or the :slant to `normal'."
