Can anybody advice me how to remove vibrations of color/lighting ?
I decreased pretrace_start but it rather not change behavior
Here are setting for radiosity

#declare ToMidnight=1-abs((_Hour+_Minute/60)-12)/12;
global_settings{
  ini_option "Antialias=yes"
  ini_option "Sampling_Method=2"
  ini_option "Antialias_Threshold=0.3"
  ini_option "Jitter=no"
  ini_option "Antialias_Depth=3"
  ini_option "Radiosity=yes"
  ambient_light sqrt(sqrt(ToMidnight^.25))
  assumed_gamma 1.2
  radiosity{
    pretrace_start 0.02
    pretrace_end   0.01
    count 80
    nearest_count 5
    error_bound 1
    recursion_limit 4
    low_error_factor .5
    gray_threshold 0.0
    minimum_reuse 0.015
    normal on
  }
}

You probably should increase count a lot, that should smooth things.  If
it's to slow then, you could use less strong antialiasing or reduce
'recursion_limit'.  Also 'minimum_reuse' and 'nearest_count' can be very
important.
