how white are Cockatoos

["Alan Gillanders" <>]

Brad,

It depends a bit on what they (the cockies) have been doing and also the 
colour temperature of ones eyes can affect the perception of white. You can 
check this out for yourself as most people have slightly different 
perceptions from each eye. A colourful garden is a good background. quickly 
change from using your right eye only to your left and then back again. If 
you do not see a difference try doing it through your bins as this will 
focus your eyes on a restricted area. You can check it is not the colour 
transfer properties of the bins by using them up side down. I find that 
greens and purples change most for me. Have fun, eyes are wonderful things.
Sulpher-crested Cockies have a yellow tint in their wings. Most people find 
whites with a blue tint to be the most "white" hence the old use of blue 
bags and the advertising of washing hanging under a blue sky.
