I understand that the sky is blue because the shorter-wavelength blue light is scattered through the atmosphere and hits our eyes from all directions. But why doesn't the narrower-wavelength purple light do the same thing?

Actually, at high altitudes, the sky IS violet, for exactly the reason you state. Violet photons are scattered more frequently than blue photons.
But the lower you go, the more and more atmosphere there is, so that more and more of the blue photons are scattered out. Combine that with the fact that the human eye doesn't see violet all that well, and sees blue quite well, and you get a blue sky.

Because the atmosphere filters the blue rays and there ya go. Be thankful you can SEE it as blue. Color-blind people can't. Have a good Friday!

It's not just that it's shorter, it's the specific range of color which gets trounced, I reckon.
