Brown or Blue Glass Bottles.

[BobUK]

Sometimes it is recommended to keep a chemical in a dark bottle.

Which gives the greater protection, brown or blue glass bottles?

I usually use brown as they are cheaper, but the supplier put a couple of blue ones in the order as samples.

Brown is better for blocking UV light.

I prefer colorless/clear, regardless. For things like developing agents, a clear bottle inside a dark cabinet is exactly as effective as a brown or blue bottle in a cabinet.

I have both clear and brown jugs, as they are kept in a cabinet I don't worry about the color. In the Air Force we used brown bottles and jugs, these were kept on a shelf but indoors with room light, and we used a lot of chemistry, D76 and DK 50, a gallon a week, so I don't know if the color made a difference.
