True or false? Interstellar dust and gas tend to absorb & scatter blue light more than red light, causing stars to appear redder than their true colors.

True. The preferential scattering of blue light by interstellar dust particles causing stars to appear redder. This is called Reddening.

The phenomenon of red shift, which causes distant stars to appear redder than they actually are, is caused by the expansion of the universe, which is uniform everywhere in the universe so the distance between far away stars grows faster than the distance between near stars.
stars, or rather galaxies that are very distant appear redder, and at a certain distance the increase in distance between very far galaxies is faster than the speed of light, and that is the end of the visible universe (but not the end of the universe)
