Here is what Sephora's website say's about the product:
What it is:
A mineral khôl eyeliner.
What it does:
The cult favorite Khôl Kajal returns for summer in an intense indigo blue. Apply it along the inside of the lower eyelid to enhance eyes instantly or draw a thick line along the upper lashes to add a modern sophistication.
What else you need to know:
Guerlain and Emilio Pucci have created an exceptional collaboration between the two prestigious houses that draws inspiration from summertime in Italy. The guiding motif of this second collaboration was inspired by the iconic “Winter Capri” print taken from the archives of the Italian ready-to-wear brand. Exclusively re-colored for this collection, it adds a joyful and elegant Pucci touch to the Guerlain products

Blu Acqua is a blue violet color. It's not quite opaque on the lid, it looks rather sheer.
I'm really torn about this one, I don't hate it but I don't love it either. It looks pretty on the water line and lower lash line when worn with a complete eye look but unfortunately it didn't last long on the water line. It blends well and applies easily without having to tug on the eye. This did not cause my eyes to water like so many other liners do. I love Guerlain but I'm very underwhelmed by this product. That's not to say that it's bad but stacked up against the other reviews I've done of Guerlain products this one just doesn't feel like it measures up. This product is looking for someone else, I wish it was me but it just wasn't meant to be.
