I got the PPG Envirobase formula, base-clear for Andulusite Blue, from PPG, and had it shot out with 3 minor variations, pulling out a bit of the black and crimson pigments. Under most lighting conditions, you would be hard pressed to tell one sprayout from the other. But PPG still has the old formulas adapted to modern paints.
I love the color, and it is what was on it when my father purchased the cabriolet new in late 1929. As you can see, the light conditions really affect the color you see.
