8 # Google Brand Specification

10 > Identity-only preset. No SVG page roster — pages are composed freely under these constraints.

12 ## I. Brand Overview
13
14 | Property | Value |
15 |---|---|
16 | Brand Name | Google |
17 | Use Cases | Product launches, developer events (Google I/O style), corporate updates, multi-product decks, ecosystem education / training |
18 | Tone | Modern, friendly, optimistic, clear, multi-color expressive |
19 | Sources | Bundled Google SVG assets; [Google Brand Resource Center](https://about.google/brand-resource-center/guidance/), reviewed 2026-07-13 |

21 ## II. Color Scheme
22
23 | Role | HEX | Provenance | Notes |
24 |---|---|---|---|
25 | primary | `#4285F4` | fact | Google Blue — extracted from `google_g_logo.svg` |
26 | secondary | `#34A853` | fact | Google Green |
27 | accent (warm) | `#FBBC05` | fact | Google Yellow |
28 | accent (alert) | `#EA4335` | fact | Google Red |
29 | text | `#202124` | approx | Standard Material / Google product UI text |
30 | bg | `#FFFFFF` | approx | Default light presentation background |
31
32 The four primary brand colors (Blue / Green / Yellow / Red) carry equal weight in Google brand usage; the `primary` / `secondary` / `accent` role split above is a slide-layout presentation hierarchy convention, not a brand prominence statement. Strategist may rotate any of the four into the dominant role per page rhythm.
33
34 ## III. Typography
35
36 | Role | Family | Weight |
37 |---|---|---|
38 | title | `"Segoe UI", "Microsoft YaHei", sans-serif` | 500–700 |
39 | body | `"Segoe UI", "Microsoft YaHei", sans-serif` | 400 |
40
41 > `Google Sans` and `Roboto` are references. PPT Master neither auto-embeds fonts nor follows CSS tails in PowerPoint. The rows above are the default Windows/Office export; replace them only with a user-confirmed target-installed face.

43 ## IV. Logo
44
45 Google uses a dual-lockup brand system — pick by context, never combine on the same page.
46
47 | File | Form | Usage |
48 |---|---|---|
49 | `../images/google_wordmark.svg` | Full "Google" wordmark (272×92) | Cover hero, ending sign-off, any moment the full brand reads at a glance |
50 | `../images/google_g_logo.svg` | Square multi-color "G" mark (24×24) | Header / footer corners, page-number neighbors, tight badges, any small-size moment where the wordmark would become illegible |
51
52 - Cover: prefer wordmark
53 - Per-page: optional — only when wordmark or G mark genuinely fits the layout; do not stamp every page
54 - Use only unmodified approved artwork and follow the official guidance for the actual context; never imply affiliation, sponsorship, or endorsement
55 - Clearspace: follow the applicable official asset guidance; never crowd the logo or place it on a busy background
56
57 ## V. Voice & Tone
58
59 - Formality: neutral
60 - Person: we / you (English), 我们 / 你 (Chinese)
61 - Emoji: allowed
62 - Abbreviations: common-abbrev-allowed
63
64 ## VI. Icon Style
65
66 - Preference: one consistent Material-aligned family; filled or stroke according to the deck context
67
68 > This is a presentation convention, not permission to imitate Google's visual identity. When the deck uses `templates/icons/`, choose one compatible family and keep weight/fill treatment consistent.
