Color Picker — HEX, RGB & HSL Converter and Chooser

This free color picker and HEX, RGB, HSL converter gives you all three color codes for any color at once — with one-click copy for each. Use the visual color chooser, type a HEX code directly, or drag the RGB sliders, and every output format updates instantly alongside a live swatch. It is the fastest way to get the exact color code you need for CSS, HTML, Figma, Photoshop or any design and development project — no format juggling, no manual math, nothing stored on a server.

Arb Digital's designers reach for a color picker and HEX converter on every brand identity and website we build. Having HEX, RGB and HSL together in one place — instead of bouncing between three separate tools — noticeably cuts the time spent on color work, which is exactly why we built this into our tools hub.

What Is a Color Picker and How Does This One Work?

A color picker lets you select a color visually and returns its code in one or more formats. This one accepts three inputs, all driving the same live output:

• Visual picker — click the color field to open your browser's native color wheel and choose any color by hue, saturation and brightness.
• HEX input — type any valid 3- or 6-digit HEX code (with or without the #) and it converts immediately.
• RGB sliders — drag the Red, Green and Blue channels independently, each from 0 to 255, for precise control.

Whichever input you use, the HEX, RGB and HSL values update together with a matching swatch. As MDN's CSS color value reference confirms, all three formats are fully supported in modern CSS and render identically — so you can copy whichever one your project or tool expects.

How to Use This Color Converter

1. Pick a color — click the swatch to open the visual wheel, type a HEX code, or drag the RGB sliders.
2. Read all three values — HEX, RGB and HSL appear instantly beside a live preview swatch.
3. Copy the format you need — each value has its own one-click Copy button.
4. Paste it anywhere — straight into your stylesheet, design tool color panel or brand guide.

HEX Codes — The Web's Default Color Format

The HEX output is the most-used format in web design. Codes like #1B3A6B appear in CSS, HTML, design tools and brand style guides everywhere. This tool outputs a 6-digit uppercase HEX code for every color you choose — copy it directly into a stylesheet, a Figma color panel, or any field that accepts a hex value. It also works in reverse as a HEX-to-RGB and HEX-to-HSL converter: paste a code from a brand guideline and instantly see it rendered as a swatch with its RGB and HSL equivalents. That HEX-to-everything workflow is the single most common task for developers who receive brand colors as HEX and need the other formats.

RGB — How Screens Actually Make Color

RGB describes color the way displays produce it: by mixing Red, Green and Blue light, each channel from 0 (off) to 255 (full). The tool shows the value as a ready-to-use CSS rgb(r, g, b) string, and the sliders let you watch in real time how each channel shifts the result — the most intuitive way to understand color mixing. RGB also matters when you need transparency: extend it to RGBA by adding a fourth value, for example rgba(27, 58, 107, 0.5) for 50% transparent navy. This picker gives you the three channel values you need to build any RGBA rule.

HSL — The Designer's Format for Building Palettes

HSL (Hue, Saturation, Lightness) is the most powerful format for working with color systematically, because it separates the three properties that actually drive design decisions:

• Hue (0–360°) — the base color's position on the wheel: 0° red, 120° green, 240° blue.
• Saturation (0–100%) — how vivid or muted: 0% is grey, 100% is the most vivid version.
• Lightness (0–100%) — how light or dark: 0% black, 100% white, 50% the pure hue.

Need a lighter button color for a hover state? Increase the lightness. Want a soft background tint? Reduce the saturation. Building a full tonal palette from one brand color? Hold the hue constant and vary only lightness. This systematic approach produces far more harmonious results than nudging HEX codes by hand — which is why experienced designers increasingly work in HSL.

Color and Accessibility — Check Your Contrast

Color choice is not only aesthetic; it is an accessibility requirement. When you set text against a background, the difference in luminance between them must be large enough to read. As the WCAG 2.1 contrast guidelines specify, normal text needs a contrast ratio of at least 4.5:1 for AA compliance, and large text at least 3:1. The HSL lightness values this tool provides are a quick sanity check — a large gap in lightness between foreground and background generally indicates adequate contrast — though for a definitive pass you should verify the exact ratio with a dedicated contrast checker before shipping.

Common Use Cases

• Converting brand colors — turn a HEX from a brand guide into RGB and HSL for different tools.
• Writing CSS — grab a copy-ready HEX, rgb() or hsl() value for stylesheets.
• Building palettes — vary HSL lightness and saturation to generate tints, shades and hover states.
• Adding transparency — read the RGB channels to build any rgba() rule.
• Matching a color from an image — sample a HEX with an eyedropper extension, then convert it here.

Best Practices for Working With Color Codes

1. Use HEX for most CSS. It is compact, universally supported and the default in nearly every design tool.
2. Use RGBA for transparency. Reach for RGB/RGBA when you need an alpha channel rather than 8-digit HEX.
3. Use HSL to create variations. Hover states, tints and shades are far easier to build by adjusting lightness and saturation.
4. Always check contrast. Verify text-to-background ratios meet WCAG AA before launch.
5. Keep a documented palette. Store your brand colors in all three formats so any tool or teammate has what they need.
