As the filter expressions are the same for both packet and color filters,
and the packet dissection pane already provides the "Prepare..." and
"Match..." filter construction functionality, I thought it would be not too
difficult to implement this. What I would propose as a solution, is to
provide a filter construction box as it is available today (bottom left),
but with a possibility to select the constructed and/or edited filter for
execution in either packet filter or color filter.

Indeed. But you need to input the filter expression by means of the
keyboard.

Some code editors (IIRC mainly Java editors) use a "class browser" and
"method browser" which allows simple selection of a given method. We could
use this principle to do the same with filterable protocol field names. This
expression builder could be used for color and packet filters within
Ethereal, and for capture filters for libpcap (based on another dictionary
of course).

Exactly! This part is already available in the "Edit" -->  "Capture
Filters..." and "Edit" --> "Display Filters..." menu items.
