It's likely a failing of many of us to look at a colourway fading from some sort of reddish to some sort of pale amber, and assume possibly amberina.
There should be vastly more amberina your side of the pond than ours - perhaps you might have a general look and see if you can find a colour match with yours - somehow to me it lacks the depth and/or darkness of what I'm used to seeing as amberina, particularly as the original C19 colour references speak of fuchsia and ruby, which this one appears not to be - but who knows - I get things wrong, often

It's well worth reading up on Locke/Shirley and their art glass inventions amongst which are Peach Blow, Burmese and Amberina - even if we never own any it makes for very interesting reading, especially being your side of the pond.
Whilst much amberina was called art glass at the time, we might not do so now as many designs would come under the heading of utility patterns - honeycomb was popular so to was optic ribbing - but these words concern the early designs, and for all I know in the ensuing c. 130 years ideas change and so do methods and colours.
This design may be from the States, but might equally be from Europe - have your tried Pamela Wessendorf's 'pressglas-pavillon.de or the other of Pamela's illustrated glass encyclopedia 'glass-musterbuch.de'. I think they are accessible via this Board.
