I am doing a Finite Difference Method for 3D heat diffusion, so I need my ListPointPlot3D to be color coded on a range from deep red to deep blue depending on the temperature of the point.

My instinct is that I should have a fourth dimension to my list of points describing the temperature at that point, e.g {1,1,1,40} would describe a temperature of 40 at the first point in my partition, and so on. Is there a plotting option that lets me range the color of a point based on this 4th parameter?

If not, do you see any other way I can do this in Mathematica? I have tried ColorFunction, but I don't want my temperature to depend on the spatial dimensions x,y,z, I want it to depend on a fourth dimension "w" where the temperatures exist.

Many thanks

(data = Append @@@
    ({RandomReal[{0, 1}, {10, 3}], 
       RandomReal[{0, 100}, 10]} //
      Transpose)) // Grid

enter image description here

n = 1;
 {Blend[{Blue, Red}, Rescale[Last[#], {0, 100}]],
 Point[Most[#]], Text[n++, Most[#], {2, 2}]} & /@ data}]
