I guess its a question of word usage whether the projective meaning of “blue” which is something like “looks blue under good lighting conditions” should still be applied when it’s not caused by reflectance.
What would you call a glass absorbing red/orange/yellow light and letting the rest through?
As I understand it, the sky does let red-yellow light through. It scatters blue light and lets red light through relatively unchanged. So it looks red-yellow near the light source and blue everywhere else.

Yes.
