I wanted to note that some additional insight on the graph provided in the previous article about Ghroth is provided in the comments section of this WordPress page. Specifically, while reds, oranges and yellows are produced as light passes through iridium complexes, these colors would be incidental. The color would more of a pale green – for a more detailed explanation please refer to the comments on the article. However, the iridium complexes would still be reddish in color themselves. I want to thank Dromicosuchus for his contribution and clarification on this matter! Fred.
