Isn't there a good reason why green bottles are used in beer making?
Because it filters out harmful light I thought?
"Green might be a hip and trendy colour for a bottle carrying a hip and
trendy beer, but it's not an ideal colour for glass when it comes to
actually storing beer. Why? Because green glass, unlike your more
traditional brown glass, lets through damaging wavelengths of ultraviolet
and visible violet, indigo and blue light. These wavelengths of light can
create off flavours in beer in a process known as 'light strike'. Aside from
beer, some clear and green bottles may also leave certain wines, medicines,
personal care products and vegetable oils vulnerable to light-induced
damage."
