The color of the wine bottle is mainly to protect the wine from UV light. Reds, which are normally aged longer, need more protection and that is why they are normally in a green bottle. Whites can be put in clear and amber bottles as they are not normally held for a long period of time. I would advise using only green bottles, the darker the better, for reds that you plan to age. If you are in a pinch and need to use a clear or amber bottle, keep it protected from sunlight and flourescent light as much as possible and do not plan on keeping it for long.
Where there's a will, I want to be in it.
