I was expecting a rich...
I was expecting a rich blue-black...didn't matter if it was more blue or more black, as long as it was intense...

But it seems like the Ohto Blue Black refill is more granite gray than anything else. When compared to the black ink cartridge that came with my fountain pen purchase, the difference is even more striking. It's like...faded black ink! =(

If you repeatedly draw over your lines, then yes, you can get a good blue black effect, but that's a lot more work than needed.

I wonder if the color was affected because I used black ink before the blue black ink? But even then, wouldn't the ink be darker, not lighter?

Anyways, that was my experience. Tell me if yours is any better!
