Bright Color

A bright color as the yellow one on this cans makes it very easy to see on a far distance, and thats a very good thing. The color also makes it stick out, so it gets the audiences attention.

The "Yellow Cans"

The Yellow cans is very easy to see in the environment because of the color.
Although I don't like them, because it reminds me of this oil cans that has been contaminated lakes and stuff. What do you guys thing?? Am I just being a "drama queen"hehe?
We talked about having for example signs made of wood paper because of this organic feeling a zoo should have, and thats why I don't see were this metal ting fits in!
But a bright color (if not yellow) would maybe be a good thing to use to make people see it, in for example the "green line".

Signage

New Wayfinding in Eastend of london, the idea of the circle for walking distance works really well.

London Zoo Branding and Wayfinding

No clarity and consistency between signs. No hierarchy. Green line trail would be hard to be seen when busy
