Ring of Fire target circle: harder to tell when out of range

I'm going to admit that it looks pretty cool now, and that was after I thought that the VFX for ring of fire couldn't get better. But there's a big problem.

Previously, you could easily tell when your target spot was out of range, because it would switch between red and green.

Now the only indication is that the center area stops having the orange glow. And the problem with using it on hilly ground is back. While you can still see the outer ring of the targeting circle, the middle area of the fire magic pattern only sort of tries to match the slope and still gets cut off unless there's something at an altitude from the ground, like grass. This makes it hard to tell when the target is valid or not.

Perhaps the outer circle could be changed back to green/red?

FWIW, I think making the target ring go gray would work. Then you could keep the elemental "theme" color, with gray being the neutral "bad target" color. That would make more sense than a green ring for fire that goes red with a bad target.
