The prevailing colour, at this season, is grey. Even the birds, pigeons and gulls, were grey, lost against a grey sky.
We found a few colourful and/or shapely details to brighten the day:
Red float, blue tarp.
Gold Seal, Red Salmon.
Rust and green grass.
Weights and reels.
I think they say "Fire Only". I also think they catch rainwater.
Rigging with floats.
I'm working on another critter video. Should have it ready by tomorrow.
