The sun is not yellow or orange as we see in books and movies. It emits all the colours in the visible spectrum (also in other spectrums as well) making it white!

Do we experience Doppler shift with our own sun? I would assume as we are in a stable orbit we wouldnt
Strictly speaking since our orbit isn’t a perfect circle we do move towards and away from the sun, so there will be some level of redshift. At those speeds there’s really no chance of seeing it without specialised tools, in the same way you don’t see redshift from a car driving past you.
