Yeah, their colors ARE subtle.
One person told me that they got their Green Cheek because they had surveyed conures and didn't really care about dramatic colors, and had heard Patagonians were super-loud and huge, so they went for the GC.
I figure that Patagonians may be whatever they are... sweet or awful. Among humans, there are Mother Theresas and Charlie Mansons, ya know!
Funny thing... I paid $500 for the Rb 33 years ago, and I ran across one for sale a little while back for the same amount.
