I was doing an online search for ink blue items but the shades I was getting for this color were all over the place. I even tried checking the Pantone site to see what they consider ink blue and got this:

This color appears to be a deep blue with a green undertone, but not quite teal.
In some pieces I saw online, it looked more purplish toned like cobalt. In others it looked like a dark navy.

Where are the color experts who can tell me what typical ink blue is like?
