The light you see from different planets is sunlight reflecting off of them. Different minerals or gases in the planets absorb different frequencies (or colours) in the sunlight's spectrum, and reflect different frequencies (colours) of light back at us.
Mars looks reddish because the surface absorbs a lot of the non-red colours in the sunlight.
Our atmosphere absorbs some more of the light, further changing the colours we end up seeing.
Except for Jupiter's Aurora lights, the planets do not generate and emit much of the light we see. If the gas giants do create some light, it will be a negligible amount compared to the sunlight.

Hi
the light from planets is a reflection of sunlight modified by the surface or atmosphere reflecting it. Mars is basically a rust ball, hence the reddish color. Jupiter and Saturn both have gaseous atmospheres that reflect mostly yellows and oranges though Saturns rings do change its color.
Venus is white because of cloud cover.
Our eyes respond in a non linear fashion at low light levels which further complicates things.

each and every physique above absolute 0 emits electromagnetic radiation over a huge selection of frequencies. the warmer the physique, the better the frequencies. Stars are warm sufficient to grant off somewhat a lot of sunshine however the Earth being plenty less warm emits ordinarily infra purple. yet a very small quantity of the radiation emitted is interior the style of seen mild in spite of the shown fact that this source of sunshine is basically approximately not something whilst in comparison with the photograph voltaic pondered from the Earth and the synthetic mild created by us. The centre of the Earth is assumed to be made up of warm nickel - iron.
