Why does HSL make more sense for design work?

HSL separates hue (the color itself) from saturation (intensity) and lightness (brightness). This maps more naturally to how humans think about adjusting colors compared to mixing RGB channels.

How do I use the contrast checker results?

WCAG guidelines require a 4.5:1 ratio for normal text and 3:1 for large text. If the tool reports a lower ratio, adjust your color's lightness to improve readability.

Can I input CMYK values?

This tool focuses on web formats (HEX, RGB, HSL). For CMYK-to-HEX conversion, multiply each CMYK component by 255 and subtract from 255 to get the RGB equivalent.

What does the 'recent colors' section store?

Every color you select or input is added to a short history list. This lets you quickly revisit previously used colors without remembering the exact code.

Color Picker Pro

Name: Color Picker Pro
Author: Zilita Team

Pick, convert, and copy colors in HEX, RGB, HSL

Introduction

Color Picker Pro lets you select, adjust, and convert colors across multiple formats including HEX, RGB, HSL, and named CSS values. It provides a visual interface with real-time preview.

What the Tool Does

The tool displays a color wheel and sliders for hue, saturation, and lightness. As you adjust values, it updates the HEX, RGB, and HSL codes instantly. You can also type a known value in any format and the picker syncs to it.

Why It Is Useful

Designers and developers constantly need to translate between color formats. A client sends a brand color as CMYK, the CSS needs HEX, and the design tool uses HSL. This tool bridges all those formats in one place.

Who Should Use It

Front-End Developers

choosing and converting colors for CSS and design systems

Graphic Designers

matching brand palette values across tools

Marketing Teams

verifying color consistency across digital assets

Students

learning color theory through interactive HSL manipulation

Features

Visual color wheel with click-to-select interaction
HEX, RGB, HSL, and named CSS color output
Copy-to-clipboard for each format
Contrast ratio checker against white and black backgrounds
Recent color history for quick reuse

How to Use It

Click on the color wheel or drag the saturation and lightness sliders to find your target color.
Read the generated codes in each format section below the picker.
Click any format's code to copy it directly to your clipboard.
Use the contrast checker to verify readability against light or dark backgrounds.

Practical Examples

Converting Brand Color to HEX

A developer receives a brand color as RGB(45, 98, 133) from the design team. Pasting it into the tool instantly shows the HEX equivalent (#2D6285) needed for the stylesheet.

Learning HSL Color Manipulation

A student experimenting with HSL learns that keeping saturation at 100% and reducing lightness to 30% produces deep, rich variants of any hue — a practical lesson in color manipulation.

Benefits

Eliminates manual conversion math between color formats
Provides instant visual feedback so you can see what a code looks like before using it
The contrast checker helps meet accessibility requirements for text readability
Recent history saves time when working with a limited palette

Tips

Use HSL for intuitive adjustments — tweak lightness to create darker or lighter shades of the same hue
Check contrast ratios against your actual background color, not just generic white or black
When matching a brand color from a PDF or image, use the eyedropper on a screenshot and then refine the values in this tool

Frequently Asked Questions

HEX is a shorthand notation using six hexadecimal characters (plus a # prefix). RGB specifies the same color using three decimal values for red, green, and blue components.
