As Dutchman myseklf: the official colour as "the traffic light is:" are rood, oranje, and groen (i.e red, orange, and green). As actual colours if you have to pick them from a Dutch colour chart with Dutch colour names tough, they'd be rood, oranje-geel, and blauw-groen (red, orange-yellow, and blue-green). No tertiary or quaternaries for us, we love them hyphenated colours.
