Here is a pictoral guide through our Solar system that is probably close to true color. All of these come from APOD.

Mercury from Mariner 10… http://antwrp.gsfc.nasa.gov/apod/ap030216.html
Venus from Galileo.. http://antwrp.gsfc.nasa.gov/apod/ap040516.html
Earth from Apollo 17… http://antwrp.gsfc.nasa.gov/apod/ap990131.html
Mars per Hubble… http://antwrp.gsfc.nasa.gov/apod/ap990705.html
Jupiter… http://antwrp.gsfc.nasa.gov/apod/ap001226.html
Moons of Jupiter mosaic… http://antwrp.gsfc.nasa.gov/apod/ap970929.html
Uranus per Voyager II… http://antwrp.gsfc.nasa.gov/apod/ap010826.html
Neptune per Voyager II… http://antwrp.gsfc.nasa.gov/apod/ap980221.html

Sun (a bit too yellowish, though)… http://antwrp.gsfc.nasa.gov/apod/ap000925.html
Sun, beautiful colors it is not… http://antwrp.gsfc.nasa.gov/apod/ap051201.html

Here is another example on how to determine star color, including our Sun:
Orion focused… http://antwrp.gsfc.nasa.gov/apod/ap030207.html
Orion defocused… http://antwrp.gsfc.nasa.gov/apod/ap980829.html

The defocus approach accentuates the more natural color of the star. The solar twins I've found seem to be all white when defocused, further evidence for a non-yellow star to place in a near, true color mosaic.
