I have this CD 126 that I'm pretty sure is a [450]. I don't even know when I picked it up but I can guarantee I didn't pay a lot for it because it's not a type I collect. It doesn't seem to be a color listed in the guide in my mind. It doesn't seem to qualify as aqua or blue aqua. I took three pictures, but none really captures the real color of it. This picture was taken indoors in natural morning light (no flash).
