Sun looks white ?

Orange is a normal color as it’s viewed from Earth, usually when the sunrise or sunset happens and it gets the color due to dust and other particles in the air. For example when there’s a huge desert storm that blows sand particles up in high air and go in the jet stream, those times a more red sunset/sunrise can happen. That’s why also during a lunar eclipse the moon turns red, the more red the more dust/particles in the air.

Less air pollutants, dry and stable airmass in your area, staying indoors too long, maybe snow fell recently and is reflecting sunlight into your eyes...

Agreed. In the UK we have recently had some really intense blue skies, for the same reason.

I guess that Covid 19, and consequently reduced air travel, may be contributing to less pollutants.

If this common theory is correct, that the orange color of the sun when near the horizon is due to blue light scattering due to dust and other particles in our atmosphere, then why don't Jupiter and Venus also look orange when they are close to the horizon?  The only color I've ever seen them is bright white, regardless of their location in the night sky.

Jupiter And Venus can be seen shortly after sunset or shortly before sunrise before there is enough sunlight that hides them again from visible sight. The reflection of the planets atmosphere is still stronger and thus appears still bright in the sky.

Because the planets are very much dimmer than the sun we detect them with the rods in our eyes, which have no perception of colour.

It's iron oxide, go take a core of snow and melt it. Then dry the bits on low heat in a pan. Test it with a magnet.. I think you know why, but are probably supposed to moderate the reason.
