They can be yellow, red or blue as we see them. However we only see some as red and blue because of the "Doppler effect". Basically because the universe is always expanding, some stars are moving towards earth and some away. When an object is moving away from you, the light waves get lengthened so we see it as more red than it actually is. When an object is moving towards you the opposite happens, the light waves get shortened and the object appears more blue. The ones that we see as yellow are moving in the same direction and at around the same speed as earth.
Hope this helped.
