Thanks to all who helped out!! The trick I came up with AFTER I sent in my question was as suggested by Gregory - that is to select 'Edit > Colours > Import from other Document'. I then selected my current Newsletter file and it pulled-in the same colours as I use there.
Magic!! Thanks for the help, (But I will have to 'dig into' the Colour Story' more when I have some time!!) Ian Whitfield
