Feature idea: use ink visualization of all inks to find new inks

This is a kind of crazy idea, but I’d use it a lot: if there was an ink visualization for all inks in the entire companion (rather than just my own), I could find inks in specific color groups, like light blue, or pale brown. No seller seems to sort inks that granularly, and Mountain Of Ink doesn’t either. So i find I’m searching through pages of all the blues, when what i need is baby blue, etc. Just a thought.

While I’m on the topic, can anyone suggest a very psle grey or very pale blue? Lighter than Kyokkou, even? Something that would be barely legible?
