Sorry, I didn't mean the old (MegaPov 0.x?) keywords, I just had
to name that values that go into the reflection block somehow.
The docs name them COLOR_REFLECTION_MIN, COLOR_REFLECTION_MAX.

Of course I tried that, but it results in no reflection at all.
Minimal scene:
camera {location <0, .1, -5> look_at 0 angle 60}
sky_sphere{pigment{granite}}
plane{y,0
pigment{color rgb 1}
finish{reflection{fresnel}}
interior{ior 1.5}
}
When using reflection{0,1 fresnel} there is a reflection,
but I wasn't sure if the result of using the range 0...1
would be the physical correct reflection, thats because I asked.
