Thank you, you're welcome!

Speaking of which, I ordered a bottle of it from Cult Pens yesterday, which should be my very first bottle of Iroshizuku. - The first interaction with Iroshizuku is Ina-Ho which I got a sample from the UK Northern Pen Show last April. It’s a pretty colour despite brown inks aren’t my thing. That ink’s also going to discontinue along with Tsukushi.

Lamy Turquoise and Waterman Inspired Blue are similar enough that if you have one you don't need the other. Both have nice shading. Lamy sheened once for me but not on command. R&K's Blue Mare, Pelikan 4001 Turquoise, Pelikan Edelstein Topaz, and Private Reserve's Naples are all extremely similar as well. If you leave the latter in a pen for a while it starts to darken, shade, and sheen. Topaz is the bluest of the bunch. When it comes to this area of the color spectrum I am a big fan of Diamine Shimmertastic Arctic Blue (it sheens, shades, and you don't have to shake the silver shimmer into suspension), Robert Oster's Havasu Falls (deep and rich color), and Robert Oster's Bondi Blue (wonderful shading). Dave virtually introduced me to Bondi Blue in one of his other videos. If you want a highly-sheening turquoise, consider Diamine's Alexandrite (admittedly a dark turquoise bordering on teal or aqua).

They are quite similar actually, not a lot of difference between them.

Perhaps try kzfaq.info/get/bejne/rN-ChtGDuay-kok.html ?

@@PenultimateDave Oh I saw that one, but they're not muted or soft. Thanks anyways!

If you look for Irongal inks you'll find a lot of them will dry a much darker colour, although some you may not want to leave in fountain pens for too long. KWZ do a range of Irongal inks that are fountain pen friendly.

Diamine's Registrar's Blue-Black (DRBB) fits that description to an extent. I don't know if Diamine's is as bright as Sanford's (I've never seen Sanford's) but Diamine's starts out as a bright blue-black, dries to a dark blue-black, and fades to black with some gray shading over a period of a week or two. As Dave mentioned it is a modern-day iron gall ink, which are safer than old-school iron galls. They're considered safe if you give it the same maintenance treatment that you would for pigment inks. I wouldn't use it in any vintage pen or pens that are difficult to disassemble. I don't use dip pens much but in my limited experience DRBB behaves well with dip pens. It's a bit more expensive than other Diamine inks. The best price I've found is at Cult Pens. If I lost my ink collection in a fire, DRBB would be on my top 3 inks to repurchase. The Pen Outpost did a KZfaq video on DRBB. They also show a sample that was created over a year prior. Their old swab is quite a bit lighter than any of my writing. I wouldn't expect any writing to be as light as their sample.

Waterman inspired blue or a blue Iroshizuku ink are well behaved and great to use in stubs of office environment

@@ExiledExia Just purchased the Asa Gao. Hopefully it fits with my Lamy 1.1

@@09198384558 great choice!

I prefer Kon Peki over Aqua Blue more.
