For projects requiring consistent color throughout, we've added these refined single-tone options:

Slate Gray

Color Properties:

Hex code: #638BA1

Color Story:

Like silent stone resting in a cold spring stream. Then a pair of bionic fingers touched it—its cool surface stirred with a quiet sense of reason. Since then, it was the breath of technology: calm, precise, alive.

Haze Gray

Color Properties:

Hex code:  #C3D2DA

Color Story:

Rough and unfinished at first, meeting the edges of industrial steel where every groove tells a story of force and function. The rugged tone transforms from raw to purposeful texture. Since then, the color stands for machinery’s truth: tough, grounded, real.

Muted Gray

Color Properties:

Hex code: #CED2D4

Color Story:

Simply the absence of color, until a morning wrapped in mist arrived, soft light brushing quiet walls. In that stillness, a place was found—subtle, tender, like a whisper across Nordic linen. Since then, warm gray has been the feeling of home waking up

Moonlight Gray

Color Properties:

Hex code: #E4E6E7

Color Story:

Moonlight gray—a shade lost to night. But under the evening sky, pressed into sculpted form, it gained weight. Depth met silence, and silence became strength. Since then, it’s the color of quiet tension—anchored, poised, unshakable.

Mist Gray

Color Properties:

Hex code:  #F2F3EC

Color Story:

Often overlooked—too quiet to draw attention. But as lines became form and models rose from sketches, it held its ground. A neutral, steady presence. Not meant to shine, but to hold everything together. Since then, it’s been the color of structure—quiet, exact, essential.

Marigold Yellow

Color Properties:

Hex code:  #FFDA47

Color Story:

Hidden deep in the earth, raw and radiant—a buried sun against coal-black seams. Discovery struck like a conductor’s touch, refining golden ore into humming voltage; Since then, this yellow stands for power’s purest truth: sun-forged, uncontainable, real.
