I recently got in an order of Robert Oster inks and decided to try out the new Summer Storm. I don't know much about it other than it was given to some Australian FP users as an "Unnamed Blue-Grey" for them to come up with a name. "Summer Storm" definitely evokes images of stormy rain clouds, but whether they appear only in Summer, I'm not sure
Here is a quick writing sample using a Pelikan M800 B on white Tomoe River:
Here on Maruman Report Pad paper and on Rhodia Dotgrid paper:
The shading is good, and the ink is quite light and reminiscent of Iro Fuyu-Syogun. Lubrication is not the greatest, it feathers some on Maruman and Rhodia, but has nice shading. I like the look of it most on Tomoe River compared to the other 2 papers. It goes down leaning more towards blue, but as it dries a tinge of lilac comes out.
Overall, I feel this is a nice ink, but not a must have. I'm a much bigger fan of some of the other inks from this line. As for blue-greys, I prefer other inks to this as well.
This is my first review, apologies if it is lacking
