What is flat color design?

Flat color design, also known as flat design, is a minimalist design style that focuses on simplicity and functionality. It is characterized by clean, open space, flat colors, crisp edges, bright colors, and two-dimensional/flat illustrations. Flat design gained huge popularity after Apple adopted it for iOS 7 in 2013. Since then, it has become one of the most popular and commonly used design styles for websites, mobile apps, software, icons, logos, and more.

Definition of Flat Design

Flat design is a minimalist design style that emphasizes usability over embellishments. It avoids textures, gradients, shadows, reflections, highlights, skeuomorphism, and other effects. The goal is to create simple, clean interface elements that focus on usability. Key characteristics of flat design include:

  • Minimalism – Flat design aims to pare down visual elements to only the essentials needed to support usability and comprehension.
  • Simplicity – Interfaces are streamlined with only necessary elements and minimal visual distractions.
  • Legibility – Easy to read typography and information hierarchy.
  • Functionality – The focus is on usability rather than visual decorations.
  • Bright colors – Vibrant colors and high contrast between elements.
  • Bold shapes – Well-defined shapes with crisp edges and lines.
  • Two dimensionality – Avoidance of techniques that give a 3D feel.
  • Flat illustrations – Icons, graphics, and illustrations are simplified without shadows or textures.
  • Responsive principles – Adapts seamlessly to any device or screen size.

By stripping away visually distracting decorations, flat design aims to enhance usability for users. Interfaces are direct and functional.

History of Flat Design

Flat design grew out of the minimalist design movements of the 20th century, including Minimalism, Bauhaus, De Stijl, Swiss design, and the International Typographic Style. Key influences and developments include:

  • Early 1900s – Architects and artists incorporated geometric shapes and primary colors into minimalist designs and architectures.
  • 1920s-1930s – The Bauhaus school pioneered minimal, functional industrial designs.
  • 1950s – Swiss graphic designers used clean typography, geometrics, and grids in poster designs.
  • 1980s-1990s – Early computer graphical user interfaces adopted simple icons and windows.
  • Early 2000s – Web 2.0 sites like MySpace popularized minimal interfaces with flat colors.
  • 2007 – iOS software was redesigned to simplify visual elements.
  • 2010 – Microsoft’s Metro design language debuted with Windows Phone 7.
  • 2013 – Apple launched iOS 7 featuring a completely flat interface.
  • 2014 – Google’s Material Design guidelines advanced flat interface design.
  • 2015 onward – Flat design continues growing in popularity across platforms.

By the 2010s, flat design evolved as a response to skeuomorphism, which renders digital interfaces to mimic real-world objects. Flat design was seen as cleaner and more progressive. Apple’s shift to flat design principles for iOS 7 was a watershed moment that contributed tremendously to the style’s rise.

Principles of Flat Design

These principles are key to creating visually appealing flat designs:

  • Simplicity – Reduce interface elements to only essentials relevant to usability goals.
  • Clarity – Ensure all aspects are easy to understand through clear visual hierarchy and information organization.
  • Functionality – Design should serve usability goals over decorative elements.
  • Consistency – Maintain visual consistency of UI elements across platforms.
  • Typography – Use minimal typography for clean, readable text.
  • Visual Contrast – Use bold colors, shapes, and negative space to create contrast.
  • Color – Vibrant, non-realistic colors enhance aesthetics and usability.
  • Layout – Structure layouts through alignment, proximity, repetition, and contrast.
  • Responsiveness – Optimize display for all devices and screens.

By focusing on these core principles, flat designs can be highly functional and aesthetically pleasing.

Benefits of Flat Design

There are many benefits to flat design that explain its immense popularity:

  • Enhances usability – Simplifies interfaces for better human-computer interactions.
  • Improves load times – Eliminating visual effects results in faster rendering and load times.
  • Compatibility – Vector-based elements make flat design responsive across devices.
  • Scannability – Clean style facilitates quick scanning of information.
  • Legibility – High contrast and minimal text improve readability.
  • Focus – Removes distractions so users focus on key info and interactions.
  • Aesthetics – Looks clean, crisp, and modern when done well.
  • Development – Simpler to code and maintain compared to complex visuals.

Flat design streamlines interfaces while still providing visually engaging experiences. When executed properly, it can greatly improve usability for users.

Examples of Flat Design

Here are some prominent examples of flat design in user interfaces:

  • Apple iOS and MacOS
  • Microsoft Windows and Office
  • Google’s Material Design
  • Facebook, Instagram, Twitter
  • Squarespace, Wix
  • YouTube, Netflix
  • Amazon, eBay
  • Medium, Pinterest

Flat principles can be widely adapted to diverse interfaces and platforms. It is commonly used for website design, mobile apps, software, illustrations, icons, logos, marketing materials, presentations, and more.

Best Practices for Flat Design

Here are some best practices for executing flat design effectively:

  • Use negative space and plenty of whitespace to prevent clutter.
  • Organize content using visual hierarchy, alignment, and groups.
  • Ensure high color and typographic contrast for readability.
  • Use grid systems and columns to structure layouts.
  • Simplify navigation menus and calls-to-action.
  • Make buttons and clickable elements obvious.
  • Use responsive layouts that adapt to mobile devices.
  • Test usability early and often during the design process.
  • Animate interactions and transitions subtly.
  • Use vector-based assets for flexibility across resolutions.

Flat design removes distractions, so quality information architecture, layouts, and thoughtful interactions are essential.

Weaknesses of Flat Design

Potential weaknesses to avoid with flat design include:

  • Reduced distinguishability – Similar, minimalist UI elements may lack identity and recognition.
  • Less visual cues – Absence of affordances can hide interactions and reduce intuitiveness.
  • Less personality – Flat style can feel generic when not aligned with brand identity.
  • Lower information density – Lots of negative space means less info on screen.
  • Accessibility issues – Disabilities may make low contrast or small touch targets challenging to use.
  • Over simplication – Excess reduction of form can remove valuable functions.
  • Requires restraint – Restrained use of decorations and effects is a skill.

Flat design risks going too far in minimalism. Designers must strike the right balance of simplicity with helpful visual indicators and brand personality.

Flat Design vs. Skeuomorphism

Flat and skeuomorphic design differ considerably:

Flat Design Skeuomorphic Design
Focuses on usability and clarity Mimics objects and textures from the real world
Simplified, non-realistic visual style Visual richness, realism, and dimensionality
Absence of stylistic flourishes Ornate details, gradients, shadows, reflections, etc.
Based on graphics, shapes, and colors Draws from physical object appearances
Clean, open negative space Dense, layered visual elements
Objective, serious tone Nostalgic, familiar, or whimsical tone

Flat design emerged largely as a reaction to skeuomorphic design. It creates forward-looking interfaces focused on functionality over form.

Conclusion

Flat design has transformed interface and experience design by embracing principles of simplicity, utility, and visual clarity. Its user-centric minimalism has resonated with designers and users worldwide across platforms.

Done thoughtfully, flat design improves usability through clean layouts, intuitive navigation, and responsive interfaces. At its core, it aims to deliver content and interactions efficiently and elegantly.

Flat design will continue evolving as technologies change but its focus on functionality and stripped down aesthetics will influence design for years to come.
