Why do almost all computer chips have green color? Like the RAM, microprocessor, motherboard are mostly of green color. Does this green color have any relation with the fact that chips are made of silicon i.e. are they green due to the presence of silicon? I've also seen brownish color motherboards. But brown color chips are less observable than the green color. I was wondering why chips have color like green or brown. Any sort of help will be appreciated. Thanks.
