Fathom Blue

[Schonyenko2]

For a comparison, go to the reunion pictures and look at Rick Thayer's 68 Gibb car. That is 68 fathom blue.
What happens when you go to a paint jobber and ask for either 70, or 68 fathom blue, is that you will get a cross match to the next closest color available in base coat clear coat, because the older colors are laquer, or enamel mixing codes. To get as close as possible to the older variations you need a scan off a car of that color, or find someone who has done it before, and has the mixing formula.
