Name of yellow Montblanc ink

[FredRydr]

I’ve had a bottle of yellow ink from the Montblanc boutique for over a decade. I’d take a photo but I’m not at home.

The bottle has no label and is one of those ribbed 30ml cube bottles, topped with the same cap used on the 60ml bottles. It was sold separately in its own box (long gone) and not connected with a special edition pen. BUT I remember being told that it is the same ink as the then-just-withdrawn Ghandi pen’s Saffron ink, but given a different name.

Anyone know what that ink’s name was/is?
