You're welcome!In case you had trouble reading the above image, I was able to track down the same info on Paintref.com and take a screenshot. Note that I had selected 1966 as the year. This chart lists the paint codes for Dupont, Glasurit, and some Sherwin-Williams.

This is a great find by Phyrman. Thanks!
I also found this and discovered that if you type in Hillman, Sunbeam or Singer you will find some colors not listed on the main Rootes pagesYou're welcome!
