Re: [Killietalk] scintillating mop colors

Lonny,

no comment on the mops, but there used to be a misconception that 
animals, in particular fish, were color blind. Not every type of fish 
has been examined, of course, but it has been well established that many 
fish do perceive colors. A search of the web will provide plenty of hits.
