I am planning to use Sage in a vector calculus course this spring. I have a plot of two simple vector fields which are everywhere orthogonal, and wish to have arrows for one field colored differently than for the other. I cannot, however, find any documentation for a "color switch", neither for the plot_vector_field() command, nor for the show() command. (It does appear that colors are manipulable in the plot_vector_field3d() command.) Is there a way to do this? Thanks.
