How To Use the Color Palette Generator: Build Better Palettes, Check Contrast, and Export Fast
Learn how to generate color palettes from scratch or images, test contrast, simulate color blindness, and export colors for CSS, Tailwind, and design systems.

Start With the Palette Method That Matches the Job
Open Color Palette Generator and decide how you want to begin. If you need inspiration, start with random generation. If you already have a hero color, use the harmony options. If a photo or brand asset already exists, start with image extraction.
This choice matters because a product UI, a landing page, a poster, and a brand refresh do not all begin the same way. Random palettes help you explore. Harmony modes help you stay structured. Image extraction helps you stay close to real visual material.
ToolsMint keeps these paths inside one workspace because palette work is iterative. You should be able to move from inspiration to validation to export without rebuilding the same colors in three different tools.
Name the Roles, Not Just the Colors
A useful palette is not just five pretty swatches. It needs roles: primary, secondary, accent, background, surface, and text. As soon as the palette starts to feel promising, think in terms of usage.
This small habit is what separates a moodboard from a working UI palette. A vibrant accent may look great as a button highlight but fail as body text. A subtle neutral may be perfect for surfaces but disappear as a border.
ToolsMint leans into practical roles because most users are not collecting colors for fun. They are trying to build a website, a dashboard, a slide deck, a social graphic, or a small design system that still feels coherent when applied.
Check Contrast Before You Fall in Love With the Palette
Once the colors look good, run the contrast checks. Look at text on background, buttons on surfaces, muted text on cards, and any accent color you plan to use for links or status messages.
This is where many palettes fail. A set can look polished in isolation and still be hard to read in a real interface. WCAG checks are not only about compliance boxes. They are about whether users can actually read, scan, and trust the interface comfortably.
ToolsMint includes the contrast matrix directly in the palette flow because accessibility should not be an afterthought added after handoff. It is faster to reject weak combinations now than to rebuild a theme later.
Use Color Blindness Simulation as a Reality Check
After contrast, preview the palette under different color-vision conditions. Watch what happens to red-green distinctions, subtle status colors, and combinations that depend too heavily on one hue family.
The goal is not perfection for every possible screen and every possible eye. The goal is to catch avoidable mistakes. If success and error states collapse into the same-looking color, or if an accent disappears against the background, that is a design problem you can fix while the palette is still flexible.
This is one reason ToolsMint is more than a random palette toy. It helps you move from "that looks nice" to "that still works when real people use it."
Export in the Format Your Workflow Actually Uses
Once the palette is stable, export it in the format your project needs. Use CSS variables for websites, Tailwind config for utility-first setups, SCSS variables for older design systems, or JSON tokens when you want a more structured handoff.
If you started from a large image, compress that image separately later if it is meant for the web. If you only needed a quick contrast check on two colors, Color Contrast Checker may be the simpler follow-up tool. The point is to keep the workflow light.
Good palette work should end with usable output, not manual transcription. ToolsMint is strongest when it saves you from retyping hex values, rebuilding shades, and rechecking the same combinations after every small change.
