Three of these colors aren't listed yet. Left to right aqua, light aqua, dark aqua and green. The third is definitely dark aqua because compared to my others with the non missing G wedge it is not green enough to be green aqua. Was sold as dark aqua and I'd agree with that. Eventually, the missing G wedge was added and you tend to see most of theses signals with the wedge than without it. Anyone have colors I don't have shown here?
