The man who taught me compliance said internal wires could be any color. This was back in the days of VDE 0160. And my certs went through LGA Nurnberg
The exception was of course the ground circuit. There was strong direction to avoid confusion with DC circuits, especially the Red for positive voltages. In the end we chose all three phase wiring would be black. If phase rotation mattered we used labels. On the topic of colors, when I was in the US Navy, I took a color blindness test and learned statistically about 20% of white caucasian males have a red/grn color deficiency. My German compliance tutor indicated this was one reason for the grn/yel striped wire for grounding.
