[yt-users] Volume render

Dear yt:
I am using volume render to visualizing the gradient in field lines.
Is there a way that I can add more sensitivity, in terms of colors to my
final image? Currently the gradient seems very limited and cannot
differentiate between near and far fields. Drive link is below
Thanks in advance
