I have some blue black in my ink collection that are all great inks, but they don’t have the right colour I was lookin for. At the Appelboom shop in Laren I browsed through a binder full of colour examples. I decided to go for a bottle of Robert Oster Midnight Sapphire. Lucky for me they had it in stock.
The ink is now in a pen with a broad nib. It flows well and the pen is writing very smoothly with it. On average, depending on paper it has medium shading.
Some might call it more of a dark blue than a blue black. It does depend on the paper but it’s a blue black on (white) Oxford paper and fountain pen friendly printer paper. In some cheap notebooks the pen writes wetter and the it becomes more of a dark blue.
What I like is when there is decent shading. The dark parts become dark blue and the lighter parts medium blue black.
I have been wanting this color for awhile. Finally pulled the trigger. I do enjoy it when laid on heavy which gives it a wonderful red sheen. I would avoid this on any nib below Medium. I don' t think you would get the same experience. I was using the Galen Leather Everyday Notebook with the original Tomoe River paper.
My blue of blues.
Although I've got quite a large collection of blue inks, this one is my favourite.
An awesome cerulean blue with great shading properties and very well behaved on top. A must-add to any ink collection as far as I'm concerned. :-)
I was looking for a very dark green ink for a long time one that was dark enough that it wouldn't look out of place in a business setting and bright enough that it was not just black with a name reminiscent of some other colour that may have been added in small amounts.
Enter RO "Green at Night" it is exactly the colour I have been looking for a green to petrol blue that goes down noce and dark but when you see it it makes you question the colour. Perfect.
The ink flows well and I would consider it to be a thin "watery" ink. This is not a bad thing at all. Even in one of my high flowing Italian pens this works a treat.
The water resistance is not good and if you are writing something that has a possibility of getting wet it will not hold up - not that many fountain pen inks will so not to dissimilar to most - other than that it is a near perfect ink and I will be adding several more to my collection as well as stocking up on my new signature colour.
The ink of my choice was not available, so Joost choose another color for me. He did a great job with that. I love the RO inks, bright, vibrant colors, great flow, very useful bottles and not unimportant: the name of the ink is on the top of the cap, so I don’t have to take all my bottles out to find the one I’m looking for. I wish all the brands did that! This turquoise is on the teal-side of the spectrum and perfectly fit with my Wahl Eversharp Signature in Jade. That is the same material as the Leonardo Furore Grande Smeraldo is made of, so that would be a perfect match too!
