Totally confused! Can I see a difference between Prosecco and Veuve Clicquot?

Veuve Clicquot on the top shelf – Valdo one down 

– 2nd label of Veuve Clicquot or a Prosecco?

Dear Veuve Clicquot Legal Eagles Team,

I trust you won't object to me writing to you but I am totally confused. I had thought that through your indefatigable and rigorous efforts a yellowy orange label on a bottle of sparkling wine indicated that this would unquestionably be Veuve Clicquot Champagne.

Imagine my surprise when I visited my local J.Sainsbury (Forest Hill, London SE23) this afternoon that confusion reigns supreme. There are a profusion of yellow/orange labels on bottles of sparkling wine. Some of these appear to be Prosecco and others Veuve Clicquot – presumably Champagne unless you have diversified into Prosecco. Sainsbury's appears to have a penchant for yellow/orange sparkling wines! 

Your fearless pursuit around a year ago of the small Italian producer – Ciro – or earlier Stefano Lubiana in Tasmania in 2001 appears to have been entirely ineffective – possibly counter-productive. Neither of these producers' wines are ever likely to grace the Sainsbury's shelves in Forest Hill, instead we have lots of attractive yellow/orange labels from sparkling brands like Canti and Valdo.

I trust you will use your well-established legal muscle to sort out this dreadful confusion. I hope you will assert Veuve Clicquot's sole right to yellow/orange labels for sparkling wines against all these other brands taking advantage of your reputation – treat it as Christmas coming early!

Consumers will surely be grateful!   

Which one is the Champagne please? 

Thoroughly confused: same colour so is the 

Canti Prosecco also a Veuve Clicquot Champagne? 

A tale of two labels: Veuve Clicquot and the offending ciropicariello 

The Cadoro label is more orange so I'm guessing 

it's Italian – so no confusion? 

Quite orange – both Proseccos?
