Hi all, is there any way to tell from the Namiki bottle what color ink I have? The cap is a bright blue color but the ink writes like a blue-black with my safari. This ink bottle shipped with my brother's Namiki Urushi pen, and did not have a cardboard case/cover of its own.

Thanks

I think you have a bottle of Namiki Blue. Would you be able to post a scan?

Note: Standard Namiki bottled ink only comes in Black and Blue. There is the Iroshizuku Series but the bottle looks completely different.

also make sure the other pen is clean...

Pilot makes a bottled BlueBlack but doesn't distribute it to the US (bstrds).

Yes. Namiki-Pilot Blue, not mixed with anything else, is not as dark as you describe. On the other hand, it is a friendly mixer with many (not all) other brands of fountain pen ink.
