I had an idea today about product coloration. So, in most cases, companies that sell products put colors in them to give them a competitive market advantage -- so that people will buy their product instead of another because of appealing color. But! This coloration uses natural resources.
If all the product makers just stopped using product coloration, they would be at no relative competitive disadvantage, and use less resources! I believe that this would be a very "green" change.
However, I'm not in any position to make this happen, and that makes me extremely angry. But I don't want to spend my life just being angry, so I can't keep thinking about it. Maybe someday, I'll be able to do something about that.
Until then, I just put thoughts like this to bed. Colorless green ideas sleep furiously.
