I'm so pleased with myself

While looking through the glasrevue, I spotted this Harrachov vase which I later saw and bought from an on-line auction (for a whole 45zł... just a little over 10 euros).
It's identified in the 1958/3-4 Czech glasrevue as a Harrachov 4/3940/23cm vase. Though the one pictured is in evening-blue, mine has a more turquoise tinge. Does anyone know the proper name for the color? And another question... Was this vase designed by Milan Metelak?
Again, I'm so proud of myself for being able to finally identify something! The only information provided in the seller's description was that it was Czech and measured 22,5cm
