Flat UI Color Palette Generator

Used by developers, writers, and creators worldwide.

The flat UI color palette generator gives you instant access to bold, saturated hues drawn from the color systems that defined modern flat design — think the vivid greens of Flat UI, the assertive reds of Material Design, and the crisp blues that shaped iOS 7. These colors work because they carry visual weight without gradients, shadows, or texture. Set the count input to pull anywhere from a tight 3-color set for focused brand exploration to a broad 8-color spread for a full UI system. Each result is randomized within the flat color spectrum, so combinations feel unexpected but cohesive — every source hue is already calibrated to the same visual intensity.

How to use

  1. Choose your options above
  2. Click Generate
  3. Copy your result

Detailed instructions

  1. Set the Number of Colors input to match how many swatches your project needs (3 for minimal, 6-8 for a full UI system).
  2. Click the generate button to produce a randomized selection of flat UI colors drawn from the core flat design spectrum.
  3. Review the color grid and click generate again as many times as needed until a combination fits your visual direction.
  4. Click any color swatch or its hex code to copy the value directly to your clipboard for use in CSS, Figma, or any design tool.
  5. Repeat with a different count to explore compact accent sets or expanded multi-role palettes from the same flat color family.

Use Cases

  • •Generating a 6-token color set to seed a Figma component library for a SaaS dashboard
  • •Picking distinct segment colors for a Chart.js data visualization with 5+ categories
  • •Prototyping status-indicator badges in a React Native app that need high-contrast fills
  • •Building a flat-style icon set in Illustrator where all icons share a unified palette
  • •Exploring primary hue options for a Notion or Pitch deck presentation theme

Tips

  • →Generate at 8 colors, then manually drop the 2 that feel off — editing down from more options beats starting from too few.
  • →Pair a flat color as your primary button color with its desaturated near-gray equivalent (mix with #ecf0f1) for hover states without leaving the flat aesthetic.
  • →Avoid using more than one warm flat color (red, orange, yellow) in the same UI — they compete for attention and blur visual hierarchy.
  • →Flat blues and greens tend to be the safest backgrounds for white text; run any yellow, coral, or teal swatch through a contrast checker before committing.
  • →For data charts, generate a palette of 6, then reorder swatches from cool to warm — this creates a natural progression that reads as a logical sequence to viewers.
  • →Save palettes that feel close but not quite right — flat colors you almost used often become accent or secondary colors in a later project.

FAQ

what are flat UI colors and where do they come from

Flat UI colors are a set of vivid, single-tone hues popularized by the Designmodo Flat UI framework around 2013 and later reinforced by Google Material Design and Apple's iOS 7 redesign. Common examples include Emerald (#2ecc71), Peter River (#3498db), and Alizarin (#e74c3c). They avoid gradients and rely on clean, fully saturated fills that scale across screen sizes.

are flat UI colors accessible enough for text overlays

It depends on the specific pairing — mid-range flat colors like yellows and light greens often fail WCAG contrast requirements when paired with white text. Always run your swatches through WebAIM's Contrast Checker before using them as backgrounds for body text or labels. Darker flat colors like Midnight Blue (#2c3e50) or Wet Asphalt (#34495e) pass more reliably.

how do I use generated flat colors as CSS variables or Tailwind tokens

Copy each hex code and declare it in your :root block — for example, --color-primary: #2ecc71. For Tailwind, add the hex values under the colors key in tailwind.config.js to extend the default palette. This gives you a centralized token you can reference across components without hardcoding hex strings.
