I am not an expert on colours but they have always held a fascination for me in Philately.
Not only because of the different colour ideas between countries but also the names used to describe them.
Then there is the problem of how the colours come over on one's computer screen compared to looking at the actual item.
I do not possess the item in question here but just wanted to say that I can see quite a big difference between Smauggie's and wt1's scans.
I only posted because Smauggie has pointed out that 'it looks to be the same colour' when from where I am looking, it definitely is not.
It's how we view it and where and the names of the colours really depends where you are in the world.
Just as a bit of fun, I see Smauggie's offering as Deep Claret and wt1's as Purple-Brown......but then I'm not in the USA !

Londonbus1....great fun.
