What color is the Sun from space? It is whiter in colour with a slight tint of yellow. Compared to the Sun being observed from Earth, it would look more whitish and bright. That is because there is no atmosphere to disseminate the blue and the background from space is black. There is no contrast to make it look more yellow.
 
a lot of astronomical photos are false colour - they're exposures of a wavelength which would usually be invisible to the naked eye, so a colour is arbitrarily assigned to the picture.
 
well, you might see a photo which is a stack of three exposures - one exposure for hydrogen's signature wavelength, one for helium, and one for carbon. and one might be coloured blue, one red and one yellow, so you get a nice colourful photo. but it might not look like that to the mk.1 eyeball.
