A couple of weeks ago Robert Oster sent me this unnamed ink to try it out and to come up with a name for it. We eventually settled on Summer Storm (though I can't say the name was my idea). The colour always reminded me of stormy or overcast weather and a summer storm I think suites it perfectly. The ink is a definitely a blue-grey ink but it has undertones of red making it subtly purple (the chromatography also reveals red) and this slightly warmer hue suites the Summer name.
