Mordekaiser keycaps: deep black without losing your bearings

A very dark set always raises the same question: does it still pass the late-night game test, curtains drawn, with the screen as the only light source? The Mordekaiser set was designed around that compromise between a grim atmosphere and genuinely readable legends.

A black that is never uniform

The palette layers several depths: blackened metal, iron gray, a heavily desaturated spectral purple, and above all orange ember veins running through the armor. Those warm highlights are what save readability: even without direct light, the eye catches a bright spot on each key and finds its position without looking straight at the keyboard.

Low light: what really helps

• Internal contrast: the bright embers stand out against the dark background of the same key
• Matte surface: PBT does not reflect the screen in a way that would hide the legend
• Placement: keeping the caps for keys you know by reflex limits visual searching

By contrast, a completely uniform black-on-black set forces you to look down every time you shift your hand: that is exactly what the ember pattern avoids here.

Construction and installation

The 12 keys are made of PBT with DYE-SUB printing, a process that dyes the material: on a dark set, this avoids the shiny worn look that quickly appears on heavily used dark keys. OEM profile, MX cross stem compatible with Cherry MX, Gateron, Kailh and Outemu, puller included.

In the same nocturnal vein, take a look at the Nocturne keycaps, even darker, the Zed keycaps for a more graphic black, or the Kha'Zix keycaps if you prefer purple accents to ember accents.

Two useful details

Are the legends backlit? No: PBT is not translucent, so the switch light passes around the key, not through it. Readability comes from the contrast of the design.

Does such a dark set show fingerprints? Much less than a glossy plastic: PBT's matte finish hides grease and does not turn shiny over time.
