HSL stands for Hue, Saturation, and Lightness. Hue is the color angle (0-360°), Saturation is the intensity (0-100%), and Lightness is how light or dark the color is (0-100%). HSL is more intuitive for humans because adjusting lightness or saturation keeps the base hue consistent.

What Is a Color Picker?

A color picker is a visual tool for selecting and converting colors across multiple formats. Instead of guessing HEX codes or memorizing RGB values, you interact with a color spectrum to find exactly the color you need, then copy the value in your preferred format — HEX, RGB, HSL, or HSB.

This color picker includes a full-spectrum selector, hue and opacity sliders, direct input fields for precise values, and a color history to keep track of colors you've used. Everything runs in your browser with instant conversion between all formats.

Understanding Color Formats

HEX — the most common web format. Six hexadecimal digits representing red, green, and blue (#FF6B6B). Compact and widely supported. RGB — decimal values from 0-255 for each channel. Easier for programmatic manipulation. HSL — hue (0-360°), saturation (0-100%), lightness (0-100%). The most intuitive format for human color selection because you can adjust brightness and saturation without changing the base hue.

How to Use This Color Picker

Click the color spectrum — Click anywhere on the color gradient panel to select a hue and saturation level.
Adjust the brightness — Use the brightness/lightness slider to make the selected color lighter or darker.
Fine-tune with inputs — Type exact values in HEX, RGB, or HSL fields for precise color specification.
Copy your color — Click the copy button to grab the color value in your preferred format — HEX, RGB, HSL, or HSB.

Tips and Best Practices

→ Start with HSL for exploration. When you're not sure what color you want, HSL's hue slider lets you sweep through the entire color wheel quickly while keeping saturation and lightness fixed.
→ Use the eyedropper for inspiration. Many browsers now support the EyeDropper API — pick any color from your screen. This tool provides the same capability for extracting colors from any source.
→ Build palettes, not individual colors. Pick a primary color, then generate complementary, analogous, or triadic harmonies. Use our Palette Generator for this.
→ Test colors in context. A color looks different on white vs. dark backgrounds, next to warm vs. cool colors, and at different sizes. Always test in your actual design context.

Frequently Asked Questions

What is a color picker?

A color picker lets you select colors visually and get code values in HEX, RGB, HSL, and HSB formats. It includes a color spectrum, hue slider, and input fields for precise color values.

What is the difference between HEX and RGB?

HEX uses six hexadecimal digits (#FF6B6B) while RGB uses decimal values (rgb(255, 107, 107)). They represent the same color space — HEX is more compact for CSS, while RGB is easier to manipulate in code.

What is HSL color?

HSL stands for Hue (color angle 0-360°), Saturation (intensity 0-100%), and Lightness (0-100%). It's more intuitive because adjusting lightness or saturation keeps the base hue consistent, unlike RGB where changing brightness requires adjusting all three channels.

What is a color picker?+

A color picker is a visual tool that lets you select colors by clicking on a color spectrum, entering numeric values, or using sliders for hue, saturation, and lightness. It outputs the selected color in standard formats (HEX, RGB, HSL) for use in CSS, design tools, and code.

What color format should I use in CSS?+

Hex (#FF6B6B) is the most common and compact. RGB/RGBA is needed when you want alpha transparency. HSL is best when you need to programmatically adjust lightness or saturation. Modern CSS also supports oklch() for perceptually uniform colors. All formats render identically in browsers.

How do I find the hex code of a color?+

Use a color picker tool like this one to visually select the color and read its hex code. You can also use browser DevTools (inspect an element and click its color swatch), the EyeDropper API in JavaScript, or screenshot tools with color sampling capabilities.
