[vtkusers] Add colour and interpolate an STL file with VTK.JS

Thank you for the explanation. I'm sorry, if I'm missing something obvious but this is my first time doing something like this.
What I need to achieve is interpolation between the points with colour to give a pressure map across the entire model.
What you have said makes sense, I'm just not sure how to change my code in order to achieve what I want to achieve..

That looks correct (respecting what you are asking vtk to draw), you seems to only have data on a couple of them where you see variation of color within some triangles.
The rest remain a single color as those values are the same and since you did not reversed the hue range, those values are probably 0.
So interpolating from 0 to 0 give you a solid color.
