On Earth the sun looks mostly white, with a slight yellowish cast:
1. The sun's actual light is mostly white, with a little yellow.
2. The atmosphere scatters away some of the blue light (as you mentioned in your question). This makes it more yellow.
3. The light is so intense it saturates even the blue receptors in your your eye, making it appear more white. (This is why you SHOULD NOT look directly at the sun!!)
4. Finally, it is surrounded by the blue appearance of the sky, giving it a slightly yellowish tint due to contrast effects.
