Which Montblanc inks are currently and were formerly in the range, in particular Permanent Blue-Black and Emerald Green?

In the ink-bottle range one finds, among others, the colours Black, Royal Blue (washable), Turquoise, Blue-Black (permanent, document-proof), Burgundy Red, Sepia Brown and Emerald Green (dark green); discontinued are, among others, Ruby Red, Smaragd Green, Love Letters and Season's Greetings (chocolate, scented). The cartridges largely correspond to the bottled range, without Turquoise. Permanent Blue-Black and the dark Emerald Green are regular components of the current range, even if availability in individual boutiques can vary.
