There are a couple ways of adding pigments to triangles.

 Both you can do with and without the union or mesh wrapper -

  union  {
triangle { <...>,<...>,<...> pigment { rgb<...> }}
triangle { <...>,<...>,<...> pigment { rgb<...> }}
triangle { <...>,<...>,<...> pigment { rgb<...> }}
triangle { <...>,<...>,<...> pigment { rgb<...> }}
         }

or

#declare T1 = texture { pigment { rgb<...> }}
#declare T2 = texture { pigment { rgb<...> }}
#declare T3 = texture { pigment { rgb<...> }}
#declare T4 = texture { pigment { rgb<...> }}

    mesh {
triangle { <...>,<...>,<...> texture {T1}}
triangle { <...>,<...>,<...> texture {T2}}
triangle { <...>,<...>,<...> texture {T3}}
triangle { <...>,<...>,<...> texture {T4}}
         }
