Alpina Blue came in different flavors from BMW, depending on the production timeframe.
For the Alpina B12 5.0/5.7 coupe, Alpina used the following blues from BMW for their vehicles:
- BLAU METALLIC (FE 86-5489)
- ALPINA BLAU METALLIC II (FQ 95-3965) - 5.7 only
- MAURITIUSBLAU METALLIC (287)
- NACHTBLAU METALLIC (FE 68-51AX)
There are other shades of purple and blue, but for this discussion, it's "blue" that matters here.
Because "AlpinaBlau" was used from different BMW colors, it's important to know which color Alpina ordered from the BMW factory for the Alpina vehicle and/or if Alpina repainted the car.
As M5 Killer correctly points out, there were different shades of AlpinaBlau.
