A vertex color map just takes UVW coordinates and turns them into colors. So normally a UVW coordinate would be something like [0.5, 05, 0] (midpoint on a texmap) or whatever, whereas a vertex color coordinate would be an RGB value that is something like [255.0, 0.0, 0.0] (red).
So the question is, how can tyFlow assign RGB values like that to UVW coordinates? And the answer is simple: the Fluid Properties operator can be used to take PhoenixFD RGB values and assign them to particle data channels. However, a texmap has no idea that particles have data channels. So we then use a Mapping operator to take the vector value of the data channel, and push it into a UVW mapping channel, so that it can be read by a vertex color texmap. Of course you'll need to adjust your Mapping operator settings to tell it to take your custom vector and place it in the mapping channel of your choice.
