Yes. I should have qualified "natural" colors in the OP, so let me be clear...
If you were to travel to each planet, how would each appear to you as far as their natural coloration? Since the Sun's surface brightness is too bright, along with possibly Mercury and Venus, then we must use a true neutral filter, or other device (e.g. strobe, pinhole projecton), that would allow us to see the object within the normal photopic (color) vision range. [Objects too bright will always appear white if the colors of the spectrum are included. Once our color cones are maxed-out, white is the result, though at a normal intensity it could easily be any color, including yellow.]
