The Best Colour Pickers for Web Design

Colour pickers solve different problems. A palette generator helps you build a set of related colours. An eyedropper samples a colour that is already visible on a screen or web page. A CSS picker helps you choose a value for a website or application.

This guide covers each type, with current options for designers and developers. If you are planning a wider website palette, start with our guide to colour theory in web design.

The Best Colour Pickers

There is no single tool that does every job well. The options below are grouped by what you need to do, rather than presented as a one-size-fits-all ranking.

Colour Palette Generators

Use a palette generator when you want to build a colour scheme from a starting colour, an image or a source of inspiration.

Adobe Color

• Adobe Color lets you create a palette from a base colour, use colour-harmony rules such as complementary or analogous, or extract colours from an uploaded image.
• You can explore palettes and use Adobe’s separate contrast checker and colour-blindness simulator to review combinations.
• It is useful for developing a scheme, but check the final text, background and interface combinations in context before using them on a live website.

Canva Color Palette Generator and Color Wheel

• Canva’s Color Palette Generator extracts a palette from an image you upload.
• Canva’s Color Wheel starts with a chosen colour and suggests complementary, monochromatic, analogous, triadic or tetradic combinations.
• These tools help with palette creation; they do not sample a pixel from a website or your desktop.

Venngage Accessible Color Palette Generator

• Venngage’s Accessible Color Palette Generator creates options from a HEX value or a randomly chosen starting colour.
• Venngage says its generated pairings have a contrast ratio of at least 4.5:1 under WCAG 2.1. Treat that as a starting point and test the actual colour pairings used for text and interface elements.
• This is the most relevant choice here when accessibility is a priority. It creates palettes; it is not an eyedropper for sampling colours from a screen.

COLOURlovers

• COLOURlovers combines a palette-creation tool with a community archive of colour palettes and patterns.
• You can browse other people’s palettes for inspiration or create one from a colour or image. The site also offers palette downloads in several formats.
• It is better suited to finding and developing ideas than to sampling a colour directly from a website.

Screen and Web-Page Colour Samplers

An eyedropper is the right choice when you want to capture a colour that is already visible in a design, image or web page.

ColorZilla

• ColorZilla is a browser extension for Chrome and Firefox with an eyedropper for sampling colours on web pages.
• It can copy sampled values and includes tools such as a page-colour analyser and CSS gradient editor.
• Because the extension needs access to page content to sample colours, review its current permissions before installing it.

ColorSnapper 2 for macOS

• ColorSnapper 2 uses a magnified view to select a pixel anywhere on a Mac screen.
• It keeps colour history and favourites and can export values in more than 30 formats for design and development work.
• It requires macOS 14.6 or later. A free trial is available, followed by a paid licence.

Instant Eyedropper Reborn for Windows and Linux

• Instant Eyedropper Reborn is the current successor to the older Windows-only Classic edition. It samples a pixel from the desktop and copies the result to the clipboard.
• The Reborn version supports Windows and Linux, including Wayland and X11 on Linux, and offers magnification, colour formats and multi-monitor support.
• The project’s licence distinguishes personal or indie use from commercial or business use. If you plan to use it for client work, confirm the terms with the developer first.

Color Picker for GNOME

• Color Picker for GNOME is a GNOME Shell extension for sampling colours from the desktop.
• It is intended for Linux users running GNOME, not as a general browser extension or palette generator. Check the extension page for compatibility with your GNOME Shell version.

CSS Colour Picker Tool

W3Schools HTML Color Picker

• W3Schools HTML Color Picker lets you choose a colour from a map, enter a value or use an HTML colour input.
• It previews the selected colour alongside examples of black and white text and shows colour values for reference.
• Use it for quick colour selection and CSS-value checks. It is not designed to sample a colour from another web page or create a full palette.

Colour Picker Components for Web Apps

A picker built into an application is different from a desktop eyedropper. It lets a person choose a colour inside your own interface; it does not sample pixels from another web page or the desktop.

Angular

@iplab/ngx-color-picker is a standalone Angular package. If your application already uses PrimeNG, consider its current InputColor component. PrimeNG’s older ColorPicker is deprecated, so use the current component documentation rather than copying older examples.

Vue

Vuetify’s v-color-picker is an option when the application uses Vuetify. It supports HEX and alpha-HEX strings, as well as RGB, HSL and HSV values, and can display custom swatches.

Blazor

MudBlazor’s MudColorPicker is an in-app component with spectrum, palette and grid views. It supports RGB, HSL and hexadecimal values, with optional transparency. It requires an interactive Blazor rendering mode.

Vanilla JavaScript

For a simple form, the browser’s native <input type="color"> may be enough. Its appearance and available controls vary between browsers and operating systems. Coloris is a richer JavaScript picker, but its latest verified upstream release is from June 2025; check its current maintenance and browser support before adding it to a new project.

How to Choose the Right Colour Picker

• To create a palette: start with Adobe Color or Canva. Try Venngage when you want contrast guidance, or COLOURlovers when you need ideas from a community archive.
• To sample a colour from a website: use a browser eyedropper such as ColorZilla. For a colour anywhere on your desktop, choose a tool that supports your operating system.
• To select a CSS value: W3Schools’ picker or the native HTML colour input can be enough for a quick check.
• To add a picker to an application: choose a component that matches your framework and check its compatibility, accessibility, licence and recent maintenance.
• To check accessibility: test the actual foreground and background colours in each state, including links, focus indicators, errors and disabled controls. A palette generator cannot validate every use of a colour in your finished design. Our UX design principles guide covers broader interface considerations.

Conclusion

Choose the tool that matches the job: create a palette, sample a colour already on screen, or add a control to an application. Before settling on a colour scheme, test it in the actual design and check that text and interface elements remain readable.

FAQs

What is the difference between a colour picker and a palette generator?

A colour picker lets you select or enter a colour. A palette generator creates a group of colours that work together. Some tools offer both, but an eyedropper is a separate feature used to sample colours from a screen or web page.

How do I pick a colour from a website?

Use a browser eyedropper such as ColorZilla to sample a visible colour from the page. Review the extension’s permissions before installing it. If the colour comes from a transparent layer, gradient or image, the sampled appearance may differ from a single CSS value in the site’s source.

Can a palette generator guarantee an accessible design?

No. A generator can help find colour pairs with suitable contrast, but you still need to test the actual text and interface combinations in context. Check different states and do not rely on colour alone to communicate important information.

Which colour picker should I use for CSS?

For a quick manual check, try the W3Schools HTML Color Picker. If you are building a form, the native HTML <input type="color"> may be sufficient. Choose a JavaScript or framework component when you need more control over the interface or supported formats.

Which colour picker works with Angular, Vue or Blazor?

Use a component designed for your framework: for example, @iplab/ngx-color-picker or PrimeNG InputColor for Angular, Vuetify’s v-color-picker for Vue, and MudBlazor’s MudColorPicker for Blazor. Check the current documentation and compatibility before adding a package to a project.

Are colour picker tools free?

Some web tools and extensions are available without a paid licence, while desktop applications such as ColorSnapper 2 require a purchase after the trial. Check each provider’s current terms, especially before using a tool for commercial work.

Which colour picker tools work on macOS, Windows and Linux?

ColorZilla is available for Chrome and Firefox. ColorSnapper 2 is for macOS. Instant Eyedropper Reborn supports Windows and Linux, subject to its business-licensing terms. Color Picker for GNOME is for GNOME desktop environments on Linux.
