How the Gradient Works

The dark gray gradient moves laterally rather than vertically. Alphas on the left side of a standard 60% board sit at roughly #2d2d2d, transitioning through #4a4a4a toward #6e6e6e on the right. Modifiers (Shift, Enter, Ctrl, etc.) hold at the middle slate value, creating visual anchors that prevent the gradient from feeling chaotic. This isn't a "rainbow" effect or a per-key gradient—it's a deliberate, slow shift that rewards under-desk lighting or natural daylight without demanding attention. The colorway pairs cleanly with silver, black, or dark gray keyboard cases; white cases create stark contrast that some find too clinical, others precisely right.

Profile Choice: OEM vs. Cherry

Two variants ship under the same SKU. OEM profile follows the sculpted standard found on most pre-built mechanical keyboards—taller cylindrical tops with aggressive row-to-row variation. Cherry profile sits lower, with subtler sculpting and shorter overall height. Both use the same PBT double-shot construction, but the typing experience diverges: OEM feels familiar if you're migrating from a stock board, while Cherry reduces finger travel distance and tends to suit extended typing sessions. The gradient renders identically on both; your choice is purely ergonomic.

Material and Construction

Double-shot molding means legends are formed from a second injection of PBT plastic, not printed or dyed. The result is a keycap where the character and the cap are fused—no surface layer to wear through. PBT's natural texture is slightly grainy, resistant to the shine that develops on ABS caps after months of use. These are not shine-through; the double-shot process here uses opaque PBT throughout, so RGB lighting will illuminate around the caps rather than through them.

What's Included

No keyboard, switches, or stabilizers included. The set covers standard ANSI layouts plus common compact variants; split spacebar or ortholinear users should verify compatibility against their specific PCB.

Who This Gradient Is For

The dark gray gradient occupies a narrow niche: users who want visual interest without thematic commitment. No IP to explain, no seasonal relevance, no color-matching challenge with desk mats. The tonal range is narrow enough to read as "professional" in office environments, distinct enough to differentiate from the stock black or white caps that ship with most entry-level boards. At 61 keys covered, it works for minimal 60% builds; at 108, it fills full-size boards without blank spots.

Common Questions

Does the gradient direction match on both OEM and Cherry variants?

Yes. The color transition runs left-to-right on both profile options. Row profiles differ, but the dye placement and legend positioning remain consistent between variants.

Will these fit my Keychron K2/K8/Logitech G Pro/etc.?

If your keyboard uses Cherry MX-style cross stems (plus-shaped, 1.4mm x 1.4mm), yes. Keychron's standard lineup, most Akko boards, Drop's CTRL/ALT, and custom builds with Gateron/Kailh switches are compatible. Logitech's Romer-G and some Razer optical switches use proprietary stems and will not fit.

How does this compare to dye-sub PBT at the same price?

Double-shot and dye-sub both offer durable legends, but through different mechanisms. Dye-sub can achieve more complex colors and gradients (since it's not limited to two plastic colors), but the legend sits at surface level. Double-shot's legend is physically embedded, impossible to wear off, but restricted to color combinations where the two plastics contrast sufficiently for readability. This set uses that constraint as a feature: gray-on-gray legends are subtle, requiring the double-shot's crisp edge definition to remain legible.

What keyboard case color works best with dark gray gradient?

Black cases absorb the darkest alpha tones, making the gradient appear to emerge from the chassis itself. Silver or gray anodized aluminum creates a tonal conversation—cool metal against cool plastic. White cases maximize contrast, which some find too stark; navy or forest green cases introduce color tension that the gradient doesn't resolve. Personal preference dominates, but black or silver cases require the least visual negotiation.
