More a Babbling topic, but I'm talking about the Sun color with some scientific observations and some astronomy pictures

I'm not talking about the star's spectral type, OBAFGK... nor the star's temperature, red giants / white dwarfs and I'm not refering to the Stefan-Boltzmann laws.

But its visual appearances to the human eye

How many Colours can our Sun display ??

From Mars the Sky can appear Red because of all the dust in the atmosphere

On Earth the Sun can give out a dramatic Green Flash before it sets

In the evening on Earth the Sun can give out a fantastic Golden Orange/Yellow color

We have a few pics of the Sun from Mars thanks to all the missions to the Red planet.
Does anyone know how Sunlight appears from places like Venus, Triton or Titan ?

I have the feeling the Sun would be perhaps a reddish pinkish appearance from Titan
