I've been looking for a Pure with Blues (no backlight) with absolutely no luck. The few places I have found them, namely mechanicalkeyboards.com, say that they are "Out of Stock"
However, I can't find any information on if the the non-backlit ones are still being produced.
I really want the blues but might have to settle for the browns, unless they are still being produced, in which case I'll just wait it out.
