Color Swatch Grid Generator
A color swatch grid generator gives designers and developers an instant visual spread of random colors — each paired with its hex code — so you can scan dozens of candidates in seconds instead of hunting through a color wheel. Set how many swatches you want (the default is 12) and filter by tone: warm for reds and oranges, cool for blues and teals, neutral for grays and off-whites, or all tones at once. Each hex code sits directly beneath its swatch block, ready to copy into Figma, a CSS file, or a Tailwind config without any conversion. It is a fast way to break out of habitual color choices early in a project.
How to use
- Choose your options above
- Click Generate
- Copy your result
Detailed instructions
- Set the Number of Swatches input to how many colors you want to evaluate — try 24 for broad exploration.
- Choose a Tone from the dropdown (Warm, Cool, Neutral, or All) to filter results to your project's color range.
- Click Generate to produce the grid of color swatches, each labeled with its hex code.
- Scan the grid visually and click any hex code you want to keep, then paste it into your design tool or stylesheet.
- If no swatches suit your needs, click Generate again for a completely new random set within the same tone filter.
Use Cases
- •Generating 24 warm-tone swatches to seed an autumn fashion lookbook in Figma before narrowing to a final palette
- •Pulling neutral hex codes for card backgrounds and surface tokens in a design system component library
- •Scanning cool-tone candidates during early-stage brand concepting to find an unexpected slate or teal direction
- •Quickly populating a Notion mood board with hex codes for a bathroom tile and paint scheme
- •Sourcing a batch of random hex values to test color-rendering logic in a frontend component under varied inputs
Tips
- →Run the same tone filter three or four times and screenshot each grid — you'll build a candidate library faster than manually picking colors.
- →Neutral tone outputs pair well with a single strong accent pulled from a warm or cool grid run; combine both in one mood board.
- →If you're designing for dark mode, generate cool-tone swatches and look for mid-range values (hex digits in the 50–99 range per channel) to avoid colors that wash out on dark backgrounds.
- →Paste shortlisted hex codes into a contrast checker immediately — a beautiful swatch can still fail accessibility thresholds for text use.
- →For print projects, after copying a hex code convert it to CMYK in your print software, since screen-generated hex colors can shift noticeably in physical print production.
- →Set the count to 6 when you're near the end of a decision — a smaller grid forces faster comparison and reduces option fatigue.
FAQ
how do I use the hex codes from a color swatch grid in CSS or Figma
Each swatch displays a six-character hex value like #3A7FBC directly beneath the color block. Click it to copy, then paste it into any CSS color property, a Figma fill field, a Tailwind config, or an Adobe Illustrator color picker — no conversion needed, hex is universally accepted.
what is the difference between warm cool and neutral tone filters
Warm filters to reds, oranges, and yellows; cool restricts results to blues, greens, and purples; neutral outputs grays, beiges, and off-whites that pair cleanly with either extreme. Choosing All gives you the full spectrum with no restrictions, which is useful for open-ended exploration.
are randomly generated hex codes safe to use in commercial projects
Yes — hex color values are not copyrightable, so any code produced here can go straight into commercial branding, web design, or print work. Before using a color for text or interactive UI elements, verify its contrast ratio against your background using a tool like the WebAIM Contrast Checker to meet WCAG AA standards.
What is a color swatch used for?
A swatch is a single named colour sample you save and reuse, so a swatch grid is a quick way to browse, compare, and collect candidate colours before committing to a palette. Designers use them to audition colours side by side. The generator lays out a grid of random swatches with hex codes, so you can scan many options at once and pick the ones that work together.
How do I save or export a swatch grid?
Copy the hex codes you like into your design tool's palette or a notes file — in Figma or Adobe apps you can paste hex values to build a saved swatch library, and in CSS you would store them as custom properties. The generator displays each swatch's hex code clearly, so capturing the ones you want is just a matter of copying the codes into wherever your project keeps its colours.
