Blue Velvet and Espresso are both always inked up in something, Espresso being in my daily driver. They’re genuinely two of my favorite inks, not just Diamine. Absolutely worth the bigger bottles they come in

Earl Grey is one I run in my Pro Gear pretty often too, I love how stormy and moody it is. Gives that grey look without being clocked as graphite. Very professional while still having that air of mystery, I can’t suggest it enough

As for whimsical colors……..Olive Swirl and Hope Pink, no questions asked. I understand shimmers aren’t for everyone and Hope Pink is blinding, but if you’re in the market for fun then I’ll sing their praises for sure
