Taxi lights are green. Green/Yellow in the ILS sensitive area (needed for LVP only).
Runways lights can be 30 meters for CAT III also. Up to CAT IIIA it will have no effect. For CAT IIIB RVR will be increased to 150m i.s.o 75m.
For take off however, some authorized air carriers, can reduce the RVR down to e.g. 125m (CATC), or even down to 75m, as a minimum. Some additional requirements are needed. One of them is CL spacing of max 15m.
