You know I can actually see where you’re coming from when you put it in those terms – it reminds me of
this fantastic article about Spyro the Dragon’s color scheme.
That said, I don’t think you’re entirely correct in this case. Go to Google Images and search for “Paramonia”. You’ll notice that there are varying shades of cyan used through Paramonia and the Paramonian Temple. Some, like the screenshot I posted earlier, are duller and feel more overcast, but there are certainly others that are more vivid and closely resemble the palette in the NnT screenshot.
What’s also noticeable when browsing Google Images is that Paramonia is very, very, cyan. Like seriously, that green blue is super vivid.
