Hullo! I thought I would whip back to Holts before reporting back to you but it's foul out...not sure I'll venture out today. I'll rely on my short-term memory
When I saw photos of Cassis bags here on TPF, it looked a bit too "ash" and dull for me but I'm wrong. It's not a heavily saturated deep, dark, dramatic wine tone...but it's not pale or pastel either.
The soft smooshy leather is pigmented enough (but I suppose that could depend on bag to bag; each one might be a little different depending on how batches turned out). The leather also had enough of a sheen on it! So it's not dry or ashy.
I suppose I could say, it reminds me of Cassis wine: if you were looking through the wine glass...it's coloured with a light hand but not a water colour or a pastel. When I think of darker, sinister & dramatic wine or burgundy shades, I instantly visualize YSL Opium ads, kwim? So it's not dramatic like that. The Cassis is not muddy but it is subdued...not bright, vibrant or sharp in colour, kwim?
Personally, I will again purse rggh or perhaps the regular antique brass hardware...just don't know. For once, I could possibly pick my first silver hardware as the mini-GSH is more subtle (the larger GSH is too bright white for me personally although it's beautiful).
I think most handbag lovers are very colour sensitive, so I hope my description helps!
