/*=============================================================================
full_colors.c
Purpose:
This function handles the precise color definitions. The input
string is expected at least three tokens, specifying three near
and three far colors. The keyword old may be used to leave any of
the old colors unchanged. See the table below for mapping of
tokens. If six colors are defined, there will be two color
surfaces; nine colors define three color surfaces etc.
Input:
(1) Pointer to MolComplexS structure.
(2) Number of macromolecular complexes.
(3) Pointer to GUIS structure, with GUI data.
(4) String with six colors.
Output:
(1) Return value.
Return value:
(1) Positive on success.
(2) Negative on failure.
Notes:
(1) Mapping tokens to colors:

| 1 | left |
