The ZBS (Zelezny Brod) factory in the Czech replublic are very fond of this particular colour (my examples of ZBS have the exact same colour shift you describe) - but this is one of the patterns/styles I haven't seen before. That doesn't mean it's not theirs, it still could be a direction to look into. Especially if there isn't any wear at the base, it might be a relatively new model. Another factory to use this colour a lot would be Moser, but their vases are usually marked at the bottom as such.
The colour is used in other countries as well, I remember we had an Austrian or French neodymium dish a while ago.
Hope this helps,
Astrid
