Morris Minor Owners Club

I'm after some help please.
I have a 1969 Trafalgar Blue saloon & am going to have the wings resprayed.
I'm sure I've a book somewhere with paint code matches ... but not here with me !
Have looked at past messgaes to see if code discussed & cannot see it, BUT, can see there are 2 shades of Trafalgar Blue ..... news to me !!
Can anyone advise (without seeing car !) if I would be light or dark colour & paint code please ?!
Many thanks.

I can't provide the codes but I can tell you that the two blues are very similar but when compared one has a slight turquise/green tinge and the other is a very neutral dark blue.
The greener shade would appear to be the one that is produced by the Minor specialists and Halfords (on special request).
