The design language

Electronic Materials Office is a nocturnal atelier: matte charcoal canvas, a single incandescent orange ember, and type that whispers rather than declares. The interface treats every screen like a darkened studio — the keyboard product photographs are the only true light source, and the UI surrenders to them. Headlines at weight 200 in GT-Flexa float in vast negative space; body text is deliberately small and humanist (Times). Color is rationed: pure white for type, a desaturated violet (#9e9eff) for links, and one orange (#f45500) CTA per page that glows with its own 30px bloom. Components stay flush to the 20px radius, borders whisper at #9d9d9d, and the only shadows in the system are those two colored halos around the primary action.

Color palette

brand

Ember Orange

#f45500

Filled primary action button — the only chromatic surface in the UI, always paired with a 30px orange halo so it glows like a filament; 30px outer glow on the primary CTA — duplicates the Ember Orange hex but exists as a box-shadow, not a fill, so the button appears lit from within

accent

Lavender Link

#9e9eff

Inline link color and the outlined secondary action border — a desaturated cool counterpoint to the warm orange ember, keeping actions readable against charcoal

neutral

Studio Charcoal

#202020

Page canvas and card surfaces — the floor of the dark gallery, never pure black so the eye can rest on edge softness

Bone White

#ffffff

Primary text, hairline borders on images, and the rare inverted surface. Carries all type hierarchy on its own

Ash Gray

#9d9d9d

Muted text, subtle card borders, inactive labels — the only middle gray in the scale, used when white is too loud

Mid Felt

#eaeaea

Light surface wash for inverted panels or modal scrims — the off-white that sits between bone and the dark canvas

Carbon

#000000

Deepest accent for icon strokes and contrast borders where the charcoal canvas is too light to hold an edge

Fallback
Inter (200/400) or Manrope (200/400)

Display and heading workhorse. Weight 200 carries every headline above 24px — the 200 weight is the signature: at 68px and 86px the letterforms dissolve into atmosphere rather than shout. Weight 400 steps in for sub-headings and card captions where a whisper isn't enough. Line-heights collapse toward 1.0 at the largest sizes so display type stacks like a column of breath.

Fallback
Söhne Buch or Inter Tight

Secondary display voice for section headers and the footer wordmark. Used at a step below GT-Flexa 200 to create tonal contrast — Tobias feels more architectural, more labeled, while GT-Flexa feels ambient. Negative letter-spacing tightens the wide proportions of the Tobias Light cut.

Source Serif 4 or PT Serif

Body text and hero paragraph copy — a deliberate serif counterpoint to the geometric display fonts. The serif adds warmth and editorial gravity to product descriptions without ever growing larger than body size.

Guidelines

Do

  • Use GT-Flexa weight 200 for every display headline at 42px and above — the whisper weight is the signature
  • Apply the Ember Orange (#f45500) filled button with its 30px rgba(245,86,0,0.6) glow exactly once per viewport
  • Keep all card radii at 20px and all button radii at 20px — never break to 4px or 8px
  • Use #9e9eff for all inline links and outlined nav actions — it is the only cool chromatic in the system
  • Hold the page canvas at #202020, not #000000 — the slight lift gives product photography room to breathe
  • Let Tobias-light 32–42px carry section labels with its -2.6px tracking — it provides the architectural voice
  • Define surface edges with 1px #9d9d9d or #ffffff borders rather than shadow or background shifts

Don’t

  • Do not use Times or any serif for headings, labels, or UI chrome — it is body copy only
  • Do not apply the Ember Orange glow to anything other than the primary CTA
  • Do not introduce additional saturated brand colors — the system is orange + violet on charcoal
  • Do not use weight 400 or above for display headlines above 42px — the 200 weight is non-negotiable
  • Do not add box-shadows to cards, images, or navigation — shadows are reserved for the two button variants
  • Do not center body copy or paragraph text — left alignment only, matching the hero headline
  • Do not round anything below 16px — the system commits to soft, large radii

Components

01

Primary CTA — Ember Button

The single filled action on any screen (Pre-order, Buy).

Background #f45500, white text at 16px GT-Flexa 400, 20px radius, horizontal padding 16px, vertical padding 1px (sits visually low and wide). Always wrapped in the 30px rgba(245,86,0,0.6) outer glow. The thin vertical padding is intentional — the button reads as a glowing bar, not a pill.

02

Secondary CTA — White Ghost Button

Companion to the Ember button when two actions sit side by side.

Transparent background, 1px #ffffff border at 20px radius, white text. Mirrors the primary CTA's dimensions but carries a softer 30px rgba(255,255,255,0.3) glow — like the orange button's monochrome echo.

03

Lavender Outlined Action

Tertiary or nav-level action (e.g. About, Updates in the header).

1px #9e9eff border, 20px radius, lavender text. Functions as a quiet link-button — never used for purchase. The violet border separates navigation actions from the orange commerce action.

04

Inline Lavender Link

Anchor text inside paragraphs or feature captions.

Color #9e9eff, no underline by default, GT-Flexa 400 16px. The only inline accent in the type system — it carries affordance without weight.

05

Video / Media Card

Hero film or product video frame.

Charcoal (#202020) background matching the canvas, 20px radius, 1px #9d9d9d or #ffffff border, contains a centered product render with a floating 20px-radius Play pill button in the lower third. No shadow — the border is the edge.

06

Feature Card

2×2 or 3×2 grid cell in the Key Features section.

Charcoal canvas (no surface lift), 20px radius, 1px #9d9d9d border, 24px internal padding, top half is a square product detail photograph with no internal padding (bleeds to the card edge, clipped by the 20px radius), bottom half holds a two-line caption in Tobias-light 32px (-1.5px tracking) or GT-Flexa 24px 400.

07

Hero Headline Block

Opening product announcement that fills the first scroll.

GT-Flexa weight 200, 68–86px, line-height 1.0–1.06, color #ffffff. No text-align override needed — left-aligned by default, tracking normal, line-height tight enough that multi-line headlines stack into a single column of light. Sits directly below the video card with a 48px gap.

08

Section Header (Tobias Voice)

Delineates major sections (e.g. KEY FEATURES).

Tobias-light 400 at 42px, letter-spacing -0.062em (-2.6px), all caps in the visual system, color #ffffff. Provides an architectural label that contrasts with the weight-200 GT-Flexa body headlines.

09

Editorial Paragraph

Body copy under hero or in product descriptions.

Times 400 16px, line-height 1.2, color #ffffff. Serif body on dark background — a deliberate humanist counterpoint to the geometric display fonts. Never grows past 16px; rarity is the point.

10

Top Navigation Bar

Persistent header across all pages.

Transparent over the charcoal canvas, no background fill, no border. Left: brand mark '● Electronic Materials Office®' in white with a small orange dot prefix. Right: two ghost links (About, Updates) in #9e9eff + 1px border, then the Ember CTA. Vertical padding ~24px, sits flush to the viewport edges with internal page padding.

11

Footer

Closing block of the page.

128px top margin from the last content block, charcoal background, Tobias-light wordmark or GT-Flexa 200 at 68px as a closing statement. No card surfaces, no borders — the footer is defined by the gap above it.

12

Play Overlay Button

Centered trigger over video frames.

White fill, #000000 text reading 'Play film', 20px radius, ~16px horizontal padding. The only white-filled button in the system — functions as the inverse of the Ember CTA.

Surfaces & elevation

Level 0

Studio Floor

#202020

Page background — the base of the gallery

Level 1

Card Matte

#202020

Feature cards and media frames sit on the same charcoal as the canvas, defined by 1px borders rather than surface shifts

Level 2

Inverted Panel

#eaeaea

Light scrim or modal surface when the system inverts

Shadow is reserved for two moments only: the orange CTA and its white ghost sibling. Every other surface sits flat against the charcoal canvas, defined by 1px #9d9d9d or #ffffff borders rather than depth. The halo shadows on the buttons aren't really 'elevation' — they're lighting, treating each button like a small lamp placed in the gallery.

Layout & imagery

Layout

Full-bleed charcoal canvas with centered max-width content (~1200px). The hero opens with a 20px-radius media card containing the product film, sitting roughly 80% viewport width, followed immediately by a multi-line GT-Flexa 200 headline that wraps across nearly the full content width. Section rhythm: one feature section with a Tobias-light all-caps label, then a 2×2 (on desktop) card grid of feature tiles. Cards use 1px #9d9d9d borders and 24px gaps between them. Generous vertical breathing — sections are separated by 48–128px of charcoal negative space rather than dividers. Navigation is a single transparent bar pinned to the top with a ghost-link cluster and one Ember CTA. No sidebar, no mega-menu, no secondary navigation.

Imagery

Imagery is product-only — close-up macro photography of the Altar I keyboard shot against pure black, lit from above so the chassis glows and keycap legends catch rim light. No lifestyle, no human hands, no environmental context. Treatment is consistently high-contrast and dark; the only color that escapes the monochrome palette is the orange power switch on the keyboard itself, which echoes the Ember Orange CTA. Images are square or 16:9, always contained within 20px-radius cards, and they bleed to the card edge (no internal padding around the photo, caption sits below the bleed). Icon style: the only iconography is the small filled circle (●) prefixing the wordmark — a single orange dot, weight ~6px.
