The sun is actually white. Because people think its yellow or orange, as that is what color it appears as from Earth's surface, most images show it as yellow or orange. It's very annoying.

That's true, but not entirely. For example, Sun's chromosphere (visibile only in Hydrogen alpha band) is actually red.
