```Or...

Clear[ri, rc, liRed, liBlue, list0];
SeedRandom[3];
ri := RandomInteger[{1, 10}];
rc := RandomInteger[];
list0 = Table[{ri, ri, ri, rc}, {100}];
{liRed, liBlue} =
Split[SortBy[list0, Last], Equal @@ Last /@ {##} &][[All, All,
1 ;; 3]];
ListPointPlot3D[{liRed, liBlue}, PlotStyle -> {Red, Blue}]
