Reader, Alex, asked me to compare Diamine’s Oxford Blue to some other related dark blue Diamine inks so I’ve done just that! I have interpreted this not in terms of Diamine’s Blue-Black inks but in terms of their darker rich blues. This means that I have skipped the much darker blues such as the 150th Anniversary 1864 Blue Black, Blue Black, and Midnigt. I have also tried to not include lighter inks such as Blue Velvet or Asa Blue, and I’ve also skipped the low saturation Denim and the much more purple Imperial Blue. The inks in this comparison are Tchakovsky, from the Music set; Tudor Blue, from the second 150th Anniversary set; Majestic Blue; Oxford Blue; Lapis Blue, a Philippines exclusive; Regency Blue, from the first 150th Anniversary set; Sargasso Sea; and Blue Pearl, Blue Flame and Shimmering Seas, all from the Shimmertastic series. I’ll admit it’s a little arbitrary, but I believe these inks are an interesting comparison.
