Why are Christmas clours redgreen?

Answer 1

Because they are the colours of the leaves and berries of the yew, the holly and the rowan tree - all important in the religion of pagan peoples of Europe on whose gods and beliefs a lot of 'modern' Christian mythology is based. Saint Nick or Saint Claus or Father Christmas or whatever you like to call him was based on Old Man Winter, the Green Man, Jack Frost and many other pagan characters symbolising winter and the rebirth of life in spring. The yew and the holly in particular symbolised life in the dead of winter. The resurrection of the christ is itself based on an older myth of spring - John Barleycorn is one example - telling of the 'death' of plants in autumn and winter and their miraculous resurrection in spring.
