Assuming you're plotting from Velocity Vectors the arrow is associated with the velocity vector and the colour is (in the above) temperature.  The Scene and Object overlays are relatively new (well 5-ish years) so before that if we wanted to overlay flow field and a scalar value we'd do what you're showing in the image. Now I'd tend to overlay a contour of temperature with vectors of velocity and alter the colourmap to avoid confusion.Â
