That's natural because all life on earth is adjusted to sun as our "white balance" but it's interesting that G type stars like the sun are considered yellow on the H-R diagram.
It's also interesting how life on planets that orbit other stars would see different colors-- for life on a planet that orbits a red star for example, that red star would be "white". Any plants on such a planet would be a different color too-- likely purple. On earth, green maximizes the energy available from photosynthesis while on a planet that orbits a red star, purple would be most efficient in converting that sun's light into energy.
