lots of blue birds

  "Blue birds, blue jays, cerulean warblers, peacocks: all blue birds, but none of them are actually blue" I stand corrected

    > none of them are actually blue The article is just trying to be controversial or something; they are actually blue. Structure colors are no less real than pigment colors. It's not an optical illusion or some glitch in human perception, bounce white light off a bluejay and pass it through a prism, a strong blue line will be apparent. That blue light really is there, therefore they really are blue. This notion that only colors coming from pigments are true colors is completely arbitrary nonsense.

      They're "true colors" but they aren't the same. Pigment colors you can generally grind up and turn into a paint, structural colors not so much. Structural colors are also often angle and polarization sensitive, not so with pigment colors.
