Free Online Color Picker: How to Pick Any Color and Get Its Code

Every designer and developer eventually needs to grab an exact color — a shade from a mockup, a brand color from a screenshot, or just a color they like the look of — and turn it into a code they can paste into CSS. A color picker is the tool that bridges that gap between "I like that color" and a usable HEX, RGB, or HSL value.

This guide covers what a color picker actually does, the difference between the color formats it outputs, and how to pick and copy a color online in seconds.

What Does a Color Picker Do?

A color picker lets you visually choose a color — usually by dragging across a hue and saturation gradient, or by sampling a pixel directly from your screen — and instantly converts that selection into the numeric formats used in code and design software: HEX, RGB, and HSL.

Without a picker, you'd have to guess numeric values and check the result manually, which is slow and imprecise. A picker turns color selection into a visual, immediate process.

HEX vs RGB vs HSL: What's the Difference?

All three formats describe the exact same color — they just express it differently, and each is more convenient in different contexts.

HEX is the most common in CSS because it's compact. RGB is useful when working with individual color channels programmatically. HSL is often preferable for design work because increasing or decreasing the lightness value alone lets you create lighter or darker variants of the same hue without recalculating anything.

How to Pick a Color Online (Step by Step)

Using the ToolzGo Color Picker takes just a few seconds:

• •Go to toolzgo.com/tools/design-tools/color-picker-online
• •Drag the color swatch, or click "Pick from screen" to sample any pixel on your display
• •The HEX, RGB, and HSL values update instantly
• •Click any value to copy it straight to your clipboard

Because the tool runs entirely in your browser, nothing you pick is ever uploaded — it's just as safe to sample colors from a private mockup as from a public image.

Using the Screen Eyedropper

Modern Chromium-based browsers (Chrome, Edge, Brave) support a native "EyeDropper" API that lets a web page sample any pixel on your entire screen, not just within the page itself. That means you can open a design file, a photo, or another application, click "Pick from screen," and sample a color from anywhere — the browser handles the screen capture, and the tool reads back the exact pixel color.

This is especially useful for:

• •Matching a brand color from a logo image
• •Grabbing a color directly out of a Figma or Photoshop screenshot
• •Sampling a shade from a photo for a palette

Frequently Asked Questions

Q: Does the eyedropper work on any website or app?

A: Yes — the "Pick from screen" button uses your browser's native EyeDropper API, which can sample any pixel on your screen, not just this page. It's supported in Chrome, Edge, and other Chromium-based browsers.

Q: Is my picked color uploaded anywhere?

A: No. Color picking and conversion happen entirely in your browser using native browser APIs — nothing is sent to a server.

Q: What formats can I copy?

A: HEX (#RRGGBB), RGB (rgb(r, g, b)), and HSL (hsl(h, s%, l%)) are all available with one-click copy.

Q: Can I keep track of colors I've picked in a session?

A: Yes — recently picked colors appear in a swatch history so you can compare and reuse shades without picking them again.

Once you've picked a base color, take it further with the ToolzGo Color Palette Generator to build a full harmonious palette around it, or check it against a background with the Contrast Checker to make sure your text stays readable.
