|  | -mat_coloring_view | - print information about the coloring and the produced index sets | 
|  | -snes_fd_color | - instruct SNES to using coloring and then MatFDColoring to compute the Jacobians | 
|  | -snes_fd_color_use_mat | - instruct SNES to color the matrix directly instead of the DM from which the matrix comes (the default) |
