Hofvijver Grijs is a nice middle-of-the-road gray (unless you prefer that it be grey) ink from PW Akkerman.
If you’ve been searching for a US source for Akkerman inks and their iconic bottles, check out Vanness Pen Shop. I’ve only ordered from here once, but had a good experience.
Squeee! Firefly Yellow is what I have in my Preppy Hightlighter and I really like it. Works great, is super-bright. Does the job.
I’ve not written with Silky Purple, but the swab reminds me of J Herbin Rose Cyclamen. The bonus is that this ink is completely mixable (mix free, get it?) with others in the Platinum Mix-Free line.
My thought on Omas Red? Not red. More of a bright pink. Meh.
Diamine is one of my favorite brands of fountain pen ink and my guess is that if you love this color, you will love the ink. Unfortunately, the color isn’t to my taste – it’s really not very dark, is it?
I looooove the way Diamine Amber swabs. The color is pretty amazing and it looks like it has some potential for shading.
As part of a mega-review, I looked at it in detail here and didn’t love it. Reviews on Goulet Pens say that the ink is great, but not for very fine nibs – that may have been my issue and I should give it another go sometime.
What is your experience with Diamine Amber?
Purple from Sheaffer is a nice, bright, cheery shade of ink. I prefer a deeper shade of purple, but for those looking for this color, Sheaffer is a good, reliable brand.
Pilot Namiki Black – a good solid black. I’ve not written with it (at least not that I remember). Have you?
Noodler’s Black is a good strong black that behaves well in most every pen. In fact, Noodler’s Black is my standard black ink.
