Hello

The following code will do what you want:

liRed = Select[list0, #1[[4]] == 1 & ][[All, 1 ;; 3]];
liBlue = Select[list0, #1[[4]] == 0 & ][[All, 1 ;; 3]];
ListPointPlot3D[{liRed, liBlue}, PlotStyle -> {Red, Blue}]

You can test it with:

Clear[ri, rc, liRed, liBlue, list0]; SeedRandom[3];
ri := RandomInteger[{1, 10}];
rc := RandomChoice[{0, 1}];
list0 = Table[{ri, ri, ri, rc}, {100}];
liRed = Select[list0, #1[[4]] == 1 & ][[All, 1 ;; 3]];
liBlue = Select[list0, #1[[4]] == 0 & ][[All, 1 ;; 3]];
ListPointPlot3D[{liRed, liBlue}, PlotStyle -> {Red, Blue}]
