On the weekend I visited Blue Pool in Dorset, England.
This is an old abandoned clay mine that has filled with water to produce an attractive pool. Apparently the colour of the pool constantly changes colour...
I didn't observe the colour changes myself, but I wasn't exactly making scientific observations, the changes didn't leap out at me, they are very subtle or very gradual if they exist at all.
But why does the pool change colour at all? (Assuming that it actually does change colour.) Is the explanation of fine clay particles diffracting light a viable explanation? I can't help question that explanation because surely the clay particles would all be randomly oriented, surely you would require alignment and some kind of group behaviour to get this effect?
Can anybody out there shed any light on this for me? Perhaps its a complex dynamical effect?
Thanks

http://www.bluepooltearooms.co.uk/" [Broken]The Blue Pool at Furzebrook constantly varies in colour. Very fine clay in suspension in the water diffacting light in different ways producing a spectrum of colour sometimes green sometimes turquoise.
