1. App Basics
YouTube is the global video sharing platform, available across Web and mobile devices
Users engage with YouTube for:
– Video discovery and playback.
– Content upload and channel management.
– Interaction via comments and subscriptions.
Brand Identity: The core value is Empowerment, Connection, and Discovery. The personality is Energetic, Immediate, and Essential. All design adheres to the principles of Content Dominance, Low Friction, and Scalability.
2. Design & Experience: The Look and Feel
Logo Usage: The YouTube Logo is the main asset.
– DO use the official logo file and maintain the required clear space.
– DON’T modify, stretch, or alter the logo’s colors or proportions.
Color System: The palette is minimal, high-contrast, and action-focused.
– YouTube Red: #FF0000 — Primary accent for the Play icon and Subscribe button.
– Almost Black: #212121 — Primary base for text (Light Mode) and backgrounds (Dark Mode).
– White: #FFFFFF — Secondary base for backgrounds (Light Mode) and text (Dark Mode).
– Medium Gray: #AAAAAA — Used for secondary text and metadata.
– Highlight Gray: #F0F0F0 — Used for subtle background differentiation.
Typography & Text Usage:
– Font Family: Roboto (Sans-serif) is used exclusively across all platforms.
– Hierarchy: Titles use Bold weight; body text uses Regular.
– Tone: Language is direct, energetic, and supportive; secondary information uses a smaller size and lighter color.
Imagery and Illustration:
– Thumbnails (Imagery): Must be high-resolution, expressive, and high-contrast to maximize clicks.
– Icons (Illustration): Geometric, clean, and minimalist (Material style). The Play icon is the core functional symbol.
UI Components & Visual Style:
– Clean, functional design following Material principles.
– Cards & Shapes: Use subtle rounded corners (4-8px radius).
Layout & Spacing: Adaptive design using a responsive grid.
– Priority: The Video Player or Thumbnail Card is always the focal point of the screen.
– Spacing: Apply an 8dp grid for all margins and padding (Grid Consistency).
Accessibility & Inclusivity (WCAG Contrast):
– All text must meet WCAG 2.1 AA standards with a minimum contrast ratio of 4.5:1 against the background color.
Brand Consistency — Do’s and Don’ts: Rules for third-party use and naming.
– DO link back to YouTube content when referencing the brand externally.
– DON’T use any variant of “YouTube” (e.g., “YT”) in the name of a third-party product.
