Foundations of Design Systems

Overview

  • Previous video focused on Design System principles (the "why").
  • This video focuses on the foundations (the "what") of Design Systems:
    • Building blocks for product experiences
    • Key components: visual styles, colors, typography, components, patterns (structures, behaviors, conventions)

Key Aspects of Design Foundations

Accessibility

  • Definition: Type of inclusive design for people with disabilities
  • Disabilities can be:
    • Permanent (e.g., blindness)
    • Temporary (e.g., broken arm)
    • Situational (e.g., low visibility)
  • Designers' decisions influence accessibility:
    • Lack of access can make individuals feel unimportant or unwelcome
  • Importance of accessibility in design systems:
    • Empowers teams to create accessible experiences at scale
    • Consider resources for learning more about accessibility

Color

  • Role of Color: Expresses personality, invokes emotions, influences behavior
  • Effective color palette considerations:
    • Selection of colors: too many can cause chaos, too few can limit flexibility
    • Importance of adapting colors for themes (e.g., dark mode)
  • Create a balanced color palette:
    • Assess colors against system functions (semantic color system)
    • Simplify color usage in designs (e.g., primary button colors)
    • Follow the 60-30-10 rule for color distribution
  • Accessibility Considerations:
    • Color contrast is crucial; tools available for measuring
    • Emphasize use of symbols/icons alongside color to convey meaning

Typography

  • Importance: Consistency, personality, and readability
  • Choosing Typefaces:
    • Collaboration with branding/marketing teams is essential
    • Aim for balance between personality, performance, and legibility
  • Type Scales:
    • Collection of font sizes/styles starting from a base size (16px)
    • Use scale factors to create harmonious font sizes
    • Ensure font sizes align with grid systems (e.g., 8-point baseline grid)
    • Hierarchical format for type scales is common (headings, body text)

Elevation

  • Purpose: Provides hierarchy and visual feedback
  • Techniques: colors, shadows, transparency, overlays
  • Best practices:
    • Be mindful of elevation use in mobile design
    • Avoid using true black for shadows; use darker color values instead

Icon Systems

  • Definition: Collection of icons that enhance usability and visual identity
  • Effective icons should be functional and recognizable
  • Testing icons with users to ensure understanding
  • Consistency in size and alignment is key
  • Develop an icon grid for dimensions, alignment, and padding

Grids and Layouts

  • Purpose: Provide structure and rhythm to designs
  • Types of Grids:
    • Column, baseline, and modular grids
    • Breakpoints adjust layout based on screen size
  • Spacing:
    • Establishes hierarchy and relationships between elements
    • Use a baseline grid for consistent spacing (e.g., 8-point grid)

Patterns

  • Definition: Reusable solutions to common problems
  • Importance of documenting patterns for common user goals
  • Conduct audits to identify patterns in user flows

Conclusion

  • The foundations of a design system are interconnected
