Is the yellow really that "acidy" bright - or is it the more usual soft, buttery colour, altered by the camera?
It's a fabby colourway, and it shows really nicely on that shape.
(Although I might be tempted to display it upside down, so that the purples and yellows show up even more. I don't fret about putting glass upside down, if it looks better that way.)
