The values for R, G, B and A (alpha) each lie between 0 and 1. The Vertex Color Node works best when **Vertex Colors** is set to Points Only (Vertex Color tag), for which exactly one color or alpha value will be saved per vertex. In Polygon Points mode, only 1 average value per vertex can be read out, or 1 value set for all polygons to which the vertex belongs. C++ or Python must be used to access the Polygon Points data structure.
