Design guidance

Overview

Narecom Cloud Databricks embodies 'Refined Technical Minimalism'—a design philosophy that strips away ornament to reveal clarity and precision. The brand serves enterprise customers managing complex ML operations; the visual language communicates trustworthiness through restraint: a warm, off-white canvas (#f9f7f4) paired with a bold crimson accent (#cd2653) that signals action and confidence. The aesthetic is neither cold nor austere; it is warm, grounded, and deliberately Japanese in its sensibility—favoring negative space, hierarchical typography, and a muted earth-tone palette that evokes both tradition and modernity. The emotional response is one of calm competence: users feel they are in the hands of experts who have thought through every detail. Voice: direct, precise, never marketing-speak. The brand speaks in active verbs and concrete outcomes. Example: 'ML Flow orchestrates your model lifecycle—from experiment to production, in one platform.'

Colors

The color system is built on a principle of 'accent-driven minimalism.' The primary accent, crimson (#cd2653), is reserved exclusively for calls-to-action, interactive focus states, and brand-critical moments; it appears sparingly but with maximum impact. The secondary palette consists of a deep navy (#1b3139) used for primary text and structural elements, paired with a warm off-white surface (#f9f7f4) that reduces eye strain and conveys approachability. Supporting colors include a professional blue (#0693e3) for tertiary actions and secondary information, and a muted gray (#6d6d6d) for disabled or de-emphasized states. The surface stack uses warm beige tones (#dcd7ca for containers, #ede8e0 for dimmed surfaces) to create subtle depth without resorting to harsh shadows. All text on light s

Typography

The type system centers on YuGothic (游ゴシック) and system sans-serif fallbacks, chosen for their clarity in both Japanese and Latin scripts and their association with contemporary Japanese corporate design. Display (56px, 700 weight, -0.02em tracking) is reserved for hero headlines and major section breaks; Headline-lg (40px, 600 weight) anchors page sections; Body-lg (20px, 400 weight) is the primary reading size for descriptive copy, set at 28px line-height for comfortable scanning. Label-md (14px, 700 weight) is used for button text and form labels, with 0.01em letter-spacing to add precision. The hierarchy is strict: never skip levels, never use display for body copy. On small labels over complex backgrounds, apply a subtle text-shadow: 0 1px 2px rgba(0, 0, 0, 0.1) to ensure legibility wi

Layout

The layout follows a 12-column fluid grid with a 1280px max-width container, centered on larger screens. Horizontal rhythm is established through the spacing scale: lg (40px) separates major sections, md (24px) separates cards and content blocks, sm (12px) separates inline elements. The gutter is consistently 24px on all sides, scaling to 12px on mobile. White space is generous—never less than 40px between sections—to allow the eye to rest and to emphasize the importance of each content block. Hero sections span full-width with 80px vertical padding; body sections use the constrained container. The page rhythm favors breathing room over density: a single headline, a paragraph of body text, and a call-to-action button are separated by at least 24px each. Cards and containers use 24px intern

Elevation & Depth

Depth is conveyed through subtle shadows and color shifts rather than dramatic layering. Level 1 (Base): the surface (#f9f7f4) with no shadow. Level 2 (Cards and containers): surface-container (#dcd7ca) with a 1px solid border at outline-variant (#b8b3ab) and a soft shadow of 0 3px 8px rgba(0, 0, 0, 0.15). Level 3 (Modals, elevated cards, hero sections): surface-container-high (#d0cbc3) with the same border and a stronger shadow of 0 8px 24px rgba(0, 0, 0, 0.12). Interactive elements (buttons, inputs) use no shadow in their default state; on hover, they shift to a slightly darker background co

Shapes

The shape philosophy is 'Architectural Clarity'—rounded corners are used sparingly and purposefully to soften hard edges without introducing whimsy. Buttons and form inputs use a 0.5rem (8px) border-radius, creating a subtle softness that feels contemporary without being playful. Cards use 0.75rem (12px) for a slightly more pronounced roundness that distinguishes them from inputs. The full-radius (9999px) is reserved for badges and pill-shaped elements (e.g., status indicators). Hero sections and full-width containers have no border-radius (0px), emphasizing their structural role. This graduat

Components

Action Elements Buttons are the primary interactive component. The button-primary uses the crimson accent (#cd2653) with white text, 48px height, 12px vertical and 32px horizontal padding, and a 0.5rem border-radius. On hover, the background shifts to a darker crimson (#b01a45) over 200ms, with no shadow added. The button-secondary uses the deep navy (#1b3139) for secondary actions (e.g., 'Learn More' links); it follows the same sizing and padding but uses white text. The button-ghost variant has a transparent background with a 1px crimson border and crimson text; on hover, it fills with the primary-container color (#f5d8e0) while maintaining the border. All buttons use label-md typography (14px, 700 weight) and never include icons without text.

Do's and Don'ts

**Do**

  • Do use the crimson accent (#cd2653) exclusively for primary CTAs, focus states, and brand-critical moments—never for body text or secondary elements.
  • Do maintain at least 40px of vertical spacing between major sections; white space is a design tool, not wasted real estate.
  • Do use the warm off-white surface (#f9f7f4) as the default background; it reduces eye strain and signals approachability.
  • Do apply the label-md typography (14px, 700 weight, 0.01em tracking) to all button text and form labels for consistency and clarity.
  • Do use the 12-column grid with a 1280px max-width container; constrain content to prevent line lengths from exceeding 75 characters.
  • Do apply the md-level shadow (0 3px 8px rgba(0, 0, 0, 0.15)) to cards and containers; it creates subtle depth without visual noise.

**Don't**

  • Don't use the crimson accent for body text, backgrounds, or non-interactive elements; it must remain reserved for actions.
  • Don't introduce new colors outside the defined palette; the system is complete and intentional.
  • Don't use gradients, blur effects, or glassmorphism; the aesthetic is grounded and material-based.
  • Don't apply border-radius to hero sections or full-width containers; sharp corners establish structural clarity.
  • Don't mix font families; YuGothic (游ゴシック) and system sans-serif are the only approved typefaces.
  • Don't use shadows stronger than the lg-level (0 8px 24px rgba(0, 0, 0, 0.12)); excessive depth creates visual clutter.
