are you set on glass? I was just going to recommend the Jade one that Maureen posted.
Renzo Jade in the picket
It also comes in a subway tile size. (and a 4x4)

slimmer tile is from Tilebar under Seaport.
Wayfair and Home Depot have it under IvyHill tile under "Newport".
Tilebar also carries the Nabi line. this is a darker green color,
that is similar size to your inspo photo:
or this inspo photo:
have you seen Fireclay Tiles? very similar to your pic above.
they also have glass.
A friend of mine did Fireclay glass tiles in this shade of green w/her soapstone counters

Here's a list of their green glass colors.
you might try looking at their greens in the other medium (and they have a ton of shapes and sizes too)

just a small sample.
if you want something a little darker, AND, in a vertical orientation, a warmer, charcoal gray
which I think would look great w/your cab color and the brass accents, along w/your flooring color. has to be the warmer shade, not a cool blue gray.
Speaking of blue,
what do you think of doing this shade of blue?
switching up the light and the runner:
I think any of these blues or blue/greens would look great w/your flooring
Slate Blue is the name of the tile on the right
