Thanks for the reply. Based on the info elsewhere on this board, Indigo Blue seems to be a later color and has a different code. I am hoping to find the cross reference for the original dark blue.

According to Morganatica Indigo Blue was used in 1969 and 1970 so could have been used on a 1971 registered car. I dont think Morgan were hard and fast with dates of changes and as we know the customer could have ordered any shade or colour then as now.
A car paint supplier should be able to cross reference paint codes. Regarding the choice between Indigo Blue over Dark Blue, I would go with which i like best as both are period correct.
Have you tried checking with the factory for the build information on the car? Cost £75 I believe but worth it for the provenance of a 50 year old car.
