All black is what Logitech colors the exterior of the packaging with. This allows for the naming to pop off the background on the left, and also is a nice backdrop for the split image of the keyboard.
The long thin edge the box was just propped up on has only the naming on one end and an image of the G19s with the screen working and the keys backlit.
Both of the smaller ends of the box look like this in the image above. Just like with all the other panels, you have the manufacturer and keyboard naming, but on the ends there is a QR code box if you want to get more information on this at the point of purchase.
The other long skinny side of the box offers the most information in text form. Between the naming and the sticker that says this isn't for resale, the same information is given that we saw in the specifications chart.
Getting much closer to the packaging, this is the information that was shown in four languages to help cover Logitech's market.
On the back of the packaging, this is where you get introduced to the features of the G19s keyboard. They point out the game mode switch, macro keys, custom colors of the back lighting, and of course the LCD screen at the top of the keyboard.
Cutting a pair of anti-tamper stickers on the side, you can then open the box to see the bold blue used to surround the keyboard inside. As an added layer of protection, Logitech simply surrounds the board with a plastic liner to keep dust and scratches off the various plastic surfaces.
