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.

Aren't Blue bottles usually used for poison in all the best Agatha Christie sort of murders? I'd always be wary of such a colour because of its associations

One of the arguments for brown bottles is that they are used in large quantities for other products in the marketplace, so availability and price are excellent. I don't believe the same applies for blue.
My preference is clear, as I store things in a cupboard, but am happy with brown growlers - I like the finger hold!
