It strikes me that, after backdating the creation date and modified (after creation date)
the color changes from black to green.
Refresh or exiting and relaunching does not change the color.
Colors in other folders are black as normal. Is this a matter of some 'setting' ?
Changing into a green font - it was my mistake...
Discovered that in the 'Change Attributes & Time" window, I had 'Set Attributes' : encrypted tagged.
I gave that a try some time back but forgot to un-tag it at the next 'Change attribute'-action.
