The planets do not really change color, but the light that they reflect is distorted as it travels through the Earth's atmosphere. The brighter a planet is in the sky, the stronger this effect is. Also when a planet is near the horizon it almost appears to twinkle, because the atmospheric disturbance is worst near the horizon because there is more air between the observer and the planet.

Hi. Answer 1 is good for Venus. Some planets actually do vary in color. Mars is one. This is due to planet-wide dust storms.

If you mean when looking at it from Earth, its due in part to the atmosphere we are looking through. Different atmospheric components and different densities can affect the light from stars and planets.
