Colors might be defined in the material ( QskGradientMaterial, Colors might be defined in the material ( QskGradientMaterial,

The main advantage of using colored points is, that the material becomes Having colored points makes the material independent of the coloring
independent of the coloring and the scene graph is able to batch the nodes and the scene graph is able to batch the geometries

However adding the color information for each point increases the memory Having the colors in the material needs less memory and avoids updates
