Your mention of blue is not mis-leading.
The other vase, that impinges on these deliberations, appears in a particularly scandinavian , I hesitate to say steel-blue, unlike RSW, and clearly distinct from previously known/identified VHJ Obal/Sklo Union colours. That blue is similar to Ruda. The greater range of 914s I see, the less convinced I am, that your amber vase saw its origins in Czechoslovakia.
With this vase, as you illustrate in amber, the grey-green is so untypically Czech that only Nemsova springs to mind, and there is still no current evidence that this factory, produced these colours.
