Googleblog Design System Deep Dive

1. Brand Overview

Googleblog (https://blog.google/) is Google’s official blog property — the place where the company talks to the world about product launches, policy moves, technical achievements, and cultural commitments. The design is exactly what you’d expect from Google: clean, accessible, and built on a disciplined system. It’s not playful like YouTube’s UI, and it’s not overly corporate like Google Cloud. It sits in the middle — approachable but professional.

The vibe is “Google’s voice, but in long-form.” Typography is crisp. Color is restrained. The grid is predictable. This isn’t a marketing microsite — it’s a content hub. The design system prioritises readability and clarity. Headlines stand out, but nothing screams for attention. The primary blue (#1a73e8) is used surgically — links, CTAs, and active states — not splashed everywhere. Neutrals dominate the canvas.

This design feels like it’s speaking to the general public, journalists, and industry watchers. It’s a place where the brand must be trustworthy and legible. The system is built for scale: hundreds of articles, multiple languages, consistent modules. They’ve leaned on Vuetify (284 v- components detected), so the implementation inherits Vuetify’s material-like spacing, breakpoints, and component logic — but softened and “Google-fied” with Google Sans and their color tokens.

I like how disciplined it is. There’s no visual noise. Even the hover states are subtle, relying on underline changes and slight color shifts. It’s a content-first design system with enough brand in it to be recognisable without overpowering the words.

2. Color System

2.1 Primary Colors

The semantic primary is rgb(26, 115, 232) / #1a73e8 — the Google Blue you’ve seen in Gmail buttons and Google Search links. It’s bright enough to be noticed, dark enough for white text to pass WCAG AA contrast. This blue is associated with trust, stability, and action in Google’s ecosystem. Compared to Facebook’s #1877f2, it’s slightly lighter and less saturated. It feels friendlier.

The blue is paired with a darker hover/active shade (#174ea6 and #1967d2) for interaction depth. They don’t use gradients — flat fills only.

2.2 Complete Palette

2.3 Color Relationships

The palette is heavy on neutrals. Blue stands out because it’s the only chromatic accent. The accessibility story is solid: #1a73e8 on white yields a contrast ratio > 4.5:1 — good for WCAG AA. The darker blues (#1967d2, #174ea6) increase contrast further for hover/focus states.

Dark mode isn’t explicitly implemented here — the palette assumes light backgrounds. If they wanted dark mode, they’d invert the neutrals and swap blue usage to maintain contrast.

2.4 Usage Guide

• Primary combos: #1a73e8 text on white, white text on #1a73e8 fills.
• Hover combos: #174ea6 or #1967d2 against white for clarity.
• Avoid: Putting blue text on #757575 or any low-contrast gray — readability drops.
• Neutral layering: Light grays for surfaces, dark grays for text — don’t mix the two for text unless you’re indicating disabled states.
• Borders: Stick to #dadce0 or #5f6368 for lines — consistent with the rest of Google’s design language.

3. Typography

3.1 Font Families

Everything is set in Google Sans, Google’s proprietary geometric sans. Fallbacks are roboto, arial, helvetica. The site also loads Noto Color Emoji for emoji rendering.

Source: Google Fonts. No Adobe Fonts, no variable fonts here.

3.2 Type Scale

(… dozens more sizes exist; the scale is dense, with many small variations between 14–20px for links, captions, and buttons.)

3.3 Hierarchy

They use a tight hierarchy: H1 at 36px, most subheads around 28px, body between 16–20px. Captions and meta at 12–14px. The scale supports both large hero headlines and dense lists without breaking rhythm. Letter-spacing tweaks (-0.5px for bold 28px) tighten uppercase headings. Uppercase captions at 12–14px add a clear visual break from body text.

4. Spacing & Layout

4.1 Spacing Scale

Base unit: 8px grid. Common values:

4.2 Layout

Breakpoints are thorough: from 320px up to 1600px, with fine-grained stops (330px, 375px, 390px, etc.). This suggests careful tuning for multiple device widths — likely maintaining line lengths and grid alignment. Vuetify’s grid system drives responsiveness.

5. Visual Elements

Border Radius: Ranges from sharp (0px) to soft (8px) to pill (48px) and round (50%). Mapping:

• 4px: Inputs, small buttons
• 8px: Cards, images
• 48px: Pill buttons
• 50%: Avatars, social icons

Shadows: Minimal use. The most common is an inset shadow rgb(218, 220, 224) 0px -1px 0px 0px inset — subtle separation lines. When used, drop shadows are light and layered (rgba(60,64,67,...)), in Material style.

Borders: 1px solid #dadce0 or #5f6368 for inputs/cards. Occasionally 5px solid #1a73e8 for emphasis blocks.

6. Components

6.1 Buttons

Variant 1 — Newsletter CTA

• Default: bg #1a73e8, text #ffffff, padding 13px 26px 11px, radius 4px, no shadow.
• Hover: Odd — transform translateX(-4px) scaleX(-1) and opacity 0. Color shift to #174ea6.
• Active: Outline 3px solid #174ea6, bg transparent, text #1a73e8.
• Focus: Outline 2px solid #174ea6, bg transparent, text #174ea6.

Variant 2 — Round outline CTA

• Default: transparent bg, text #1967d2, radius 48px.
• Hover: bg #1a73e8, text white, border 2px solid #e8f0fe.

• Focus: Outline 2px solid #174ea6, box-shadow #7baaf7 0 0 0 3px.

Variant 3 — White pill

6.2 Links

Six styles, all no underline by default, underline on hover. Colors map to palette: primary blue, neutral gray, black, white, deep blue, dark gray. Hover always shifts to #174ea6.

6.3 Forms

Text inputs: bg white, border 1px solid #dadce0, radius 4px, padding 0 16px. Focus: border 0, outline 2px solid #174ea6, box-shadow rgba(49, 134, 255, 0.2) 0 0 5px 8px.

Select dropdowns: transparent bg, no border, padding right 24px. Focus: outline 2px solid #174ea6, box-shadow #7baaf7 0 0 0 3px.
