Green stars are colder, hotter, smaller or bigger than Sun? And violet stars?

Green and violet stars don't exist in the real world. Sometimes a yellow star in a binary pair with a red star looks to be tinged green, but that's a contrast effect, not a true colour.

Sometimes, in old books , I saw the "F" stars represented with green colour. So, in my childhood I thought that green stars did exist. It was much later that I discovered that was not true.

There is a very good discussion on this matter here:
