Any for a rainbow swim?

This is taken from Illoura Reserve in Balmain East. I'm looking back towards Darling Harbour and Sydney CBD. I know the selective colour thing is a bit of a gimmick or cliche. But I was hmmm "doodling" on iPad while traveling home (see yesterday's blip for answers). And I thought the coloured water could use a boost. Anyway this park has a series of ladders down into the water. I'm sure there is a reason, I may have to do some googling to find out. Our maybe I'll have to come back to this spot a few more times and ensure that includes a low tide.
