You are looking at the underside of a bridge. Imagine you’re standing on top of that bridge and you see the symbols in the water, what could they mean?

The hint here was: reflection. The symbols are mirrored and put together, so maybe try to see them as numbers? Try to put them in the order of the colours you spot on the bridge.

Alright, ask and you will get answers. The correct password here is: ‘7152’. See how the ‘7’ is the last blue symbol? The M looking symbol in red is the number 1. The light blue symbol is two ‘fives’ and the green symbol is two ‘twos’.
