What is the color of the sun outside the atmosphere of the earth?

The sun looks nearly white from space. The way sunlight is absorbed and scattered in the atmosphere give us both the blue sky and the yellow (noon) to red (sunset) solar colours we perceive, as well as the limitations and optimisations of the rods and cones in our eyes. The sun also emits a lot of radiation in colours we can't see, for example infra red and ultra violet wavelengths. The colour of a star is determined by its temperature.
