The sun is yellow. Being orange wouldn’t drastically change the color of everything we see. Pure sunlight is like 4300K in color temeprature, pure white is about 5000K, but clear sky daylight, the actual summation of light, is more like 6500K. This is because rayleigh scattering in the atmosphere shines blue light towards us across the whole sky. You’re seeing bright blue sky, the bright blue sky is shining on your daily life. This is why cloudy days are gray. The clouds are blocking enough of the blue to create a more neutral pure white.
The sun is tinted as hell in smog, though. I got a taste of classic Los Angeles in recent Indian winter.

No, the sun’s real colour image is white, but due to our nitrogen-oxygen and ozone layer atmosphere filtering certain light, it comes out blue, iirc.

The sun is a G-class star. It’s yellow or yellow-white by classification. The order from blue to red is OBAFGKM, with white being an A leaning towards an F. The perceived earthbound color of Sol skews further yellow because of the aforentioned blue-scattering.

Well… That’s the particular reason I’m keyed into it. I haven’t actually ventured far enough to actually need the KGBFOAM mnemonic. However, I am currently docked on the Distant Worlds 3 carrier. DW3 just launched on the 18th. I believe it’s near Colonia right now, at the planet of death, where the land able planet is in a jet cone.

Where the peak is depends on how you measure it. Wavelength or frequency gives different curves. If measures as a perfect blackbody the peak is green (which is connected to why chlorophyll took off, even though it's less efficient for energy capture). But we get all visible light to some degree, so its color is white. Classification has a different meaning than what it looks like.
