(Interesting Christmas facts)
A Christmas decoration is any of several types of ornamentation used at Christmas time. The traditional colours of Christmas are pine green (evergreen), snow white, and heart red. Blue and white are often used to represent winter, or sometimes Hanukkah, which occurs around the same time. Gold and silver are also very common, as are just about any other metallic colours. Typical images on Christmas decorations include Baby Jesus, Father Christmas, Santa Claus, and the star of Bethlehem. Typical winter icons include snowflakes, snowmen, icicles, and even penguins and polar bears. (source: wikipedia)
