What is GMK CYL Prussian Blue?GMK CYL Prussian Blue is a custom keycap set to be manufactured in the Cherry profile by
GMK Electronic Design GmbH. Prussian Blue's design celebrates the languages of Poland and Germany, as the former Kingdom of Prussia intersected both of these modern nations.
These MX-compatible keycaps will be made from ABS plastic and doubleshot legends (with UV front-print where needed). GMK Prussian Blue uses a simple color scheme with a GMK stock white (CP) for its legends and a custom color for the base: RAL 230 20 20 (
Preußischblau).

Base KitThe
Base Kit will support both standard US ANSI and the modern Polish Programmers’ keyboard localizations. This kit provides support for 60%, 65%, 75%, TKL, Alice, and 1800 layouts as well as “4-key” physical support for many 40% layouts.
Child KitsThe
Compatibility Kit kit provides additional size and legend compatibility beyond what is included in the base kit, including a 6u spacebar, 1.5u System keys, Numpad equals, and more 40s support, et cetera. Windowed keys for Number Lock, Caps Lock, and Scroll Lock LED indicators are also included.
The
NorDEUK Kit provides support for German, Swedish, Danish, Norwegian, and UK/Irish layouts.
When combined with the base and NorDEUK kits, the
German Mods kit provides the keys necessary to recreate several full German-language keyboard layouts (like ANSI-DE and HHKB-DE), similar to the
German Base Kit previously offered in 2022.

Prussian Blue, the chemicalPrussian Blue is a
chemical compound originally discovered in Berlin at the turn of the 18th century. It has been used in a variety of settings from art (Japanese woodblock painting) to architecture (a traditional blueprint dye) to medicine (a treatment for heavy metal poisoning).
Prussian Blue was also used for nearly two centuries to dye the military uniforms of the Kingdom of Prussia. The RAL standard and this keyset draw from this darker variant, and GMK Prussian Blue’s kitting takes further inspiration from the history of the Kingdom of Prussia itself.
The Kingdom of PrussiaThe
Kingdom of Prussia was established circa 1701 and existed until approximately 1918. Its borders changed frequently, with many of its parts split into separate enclaves and exclaves. Though it was ruled by a German-speaking monarchy, its reality was far more diverse, including regions of Germans, Poles, Lithuanians, and Silesians. For most of its existence, however, the majority of Prussian territory lay within the current borders of Germany and Poland.
