no but that's a different way of reaching blue than the normal way. rather than being pigmented, the physical material structure of the feathers is made up of effectively a keratin sponge full of small air pockets, and when white light strikes those pockets, most wavelengths of visual light cancel each other out, while blue is able to reflect and escape the structure.
so if you really fucked up a Bluejays feather what colour would it be
The natural pigmentation of blue jay feathers is brown, though I suppose it depends on how you fucked it up. I suspect that, being made of keratin, it would be an off-white if you were to grind it into a fine enough powder (speculation because I don't want to do research it's like midnight).
cool as hell! The link there is to the Yosemite park page on this.
