You're RIGHT! Caran d'Ache does make a KLEIN Blue ink! Oh my goodness! I did not know that he held a patent for the color? Maybe an official Pantone color number too?
The black label was a handsome piece indeed. The dial had a nice glossy sheen to it. Journe does do an excellent job on most of their designs. And the Centigraphe is so nice and thin! I like my watches thin!
Somehow, I find blue very calming. Seeing some blue Yves Klein paintings and/or sculptures maybe just what the doctor ordered! I also find Rothko paintings very soothing too. Yve's shade of blue is also bright and invigorating. It'd be nice to have a fountain pen ink that's like that!
I really like the Centigraphe. It's one of my favorite pieces from the brand. I find most chronographs don't always look pretty - since they look all busy and clumsy with their sub dials. But the Centigraphe is one of the few that I like!
