## Summary

Free online color picker and converter. Pick any color and instantly get HEX, RGB, and HSL values. Copy color codes with one click.

## What It Is

A Color Picker & Converter is a tool that lets you visually select any color and instantly get its value in multiple formats: HEX (used in HTML/CSS), RGB (Red, Green, Blue), and HSL (Hue, Saturation, Lightness). With over 16.7 million possible colors in the standard RGB color space (256 x 256 x 256), precise color values are essential for consistent design across screens and platforms.

Designers and developers constantly need to convert between color formats when working with CSS, design tools like Figma and Sketch, and brand guidelines that may specify colors in different notations. A brand guideline might list Pantone and HEX values, while your CSS needs rgb() or hsl() syntax. This tool provides instant bidirectional conversion between all three formats — change any value and the others update in real time.

Pick a color visually using the interactive color picker, or enter a value in any format to see the equivalents. The CSS-ready output means you can copy rgb(255, 87, 51) or hsl(11, 100%, 60%) directly into your stylesheet. Everything runs in your browser with zero data sent anywhere, making it safe for proprietary brand colors and client work.

## How It Works

Colors on screens are produced using the RGB additive color model, where red, green, and blue light combine at varying intensities. Each channel ranges from 0 (off) to 255 (full brightness), creating 256^3 = 16,777,216 possible colors. When all three channels are at 255, you get white; all at 0 gives black. This is the opposite of print (CMYK), which uses subtractive mixing.

HEX notation is simply a compact way to write RGB values using hexadecimal (base-16) numbers. The color #FF5733 means R=FF (255), G=57 (87), B=33 (51). Three-digit shorthand like #F00 expands to #FF0000. HEX became the standard in CSS because it is compact and was supported from the earliest HTML specifications.

HSL (Hue, Saturation, Lightness) was designed to be more intuitive for humans. Hue is the color angle on a 360-degree color wheel (0/360 = red, 120 = green, 240 = blue). Saturation controls intensity (0% = gray, 100% = vivid). Lightness controls brightness (0% = black, 50% = pure color, 100% = white). HSL makes it easy to create color variations: keep the hue constant, adjust saturation for muted vs vivid variants, and adjust lightness for dark vs light shades — perfect for generating consistent color palettes from a single brand color.

## Use Cases

- Converting brand guideline colors between formats — design specs might list HEX values while your CSS framework uses HSL for theme variables.
- Building design systems and component libraries where consistent color tokens need to be defined in multiple formats across CSS, JavaScript, and design tools.
- Checking WCAG accessibility contrast ratios by picking foreground and background colors to ensure text meets the 4.5:1 minimum contrast ratio for normal text.
- Creating data visualization palettes where you need evenly spaced hues (using HSL's degree-based hue) for charts, graphs, and dashboards.
- Theming UI components by adjusting HSL lightness values to generate hover states, disabled states, and dark mode variants from a single base color.
- Matching colors from a screenshot or mockup by entering an approximate HEX value and fine-tuning it visually with the color picker.

## Features

- Visual color picker with large preview swatch
- Instant conversion between HEX, RGB, and HSL formats
- One-click copy for any color format
- Direct HEX input with validation
- CSS-ready output values (rgb() and hsl() syntax)
- Works entirely in your browser

## How To Use

- Click the color picker to visually select a color.
- Or type a HEX value directly (e.g., #ff5733).
- RGB and HSL values update automatically.
- Click 'Copy' next to any format to copy the value.

## Tips

- Use HSL when you need color variations: keep the same hue and saturation, then adjust lightness to create hover states (5-10% darker), disabled states (higher lightness, lower saturation), and dark mode variants.
- For accessibility, ensure a minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text (WCAG AA). Tools like this color picker help you find exact values that meet these requirements.
- Consider color blindness in your designs — roughly 8% of men and 0.5% of women have some form of color vision deficiency. Avoid relying solely on red/green differences to convey meaning.
- Use CSS custom properties (variables) with HSL values for maximum flexibility: --brand-h: 211; --brand-s: 100%; --brand-l: 50%; then compose colors with hsl(var(--brand-h), var(--brand-s), var(--brand-l)).
- When converting colors for print, remember that RGB/HEX cannot perfectly represent CMYK colors. Some vivid screen colors (especially bright greens and blues) fall outside the printable CMYK gamut.

## FAQ

### What is the difference between HEX and RGB?

HEX and RGB represent the same colors. HEX uses hexadecimal notation (#ff5733) while RGB uses decimal values (rgb(255, 87, 51)). HEX is more compact and commonly used in CSS, while RGB is easier to read and manipulate programmatically.

### What is HSL?

HSL stands for Hue, Saturation, Lightness. Hue is the color angle (0-360 degrees), Saturation is the color intensity (0-100%), and Lightness is how bright the color is (0-100%). HSL is often more intuitive for picking color variations.

### How do I use these color values in CSS?

In CSS, you can use any format: color: #ff5733; or color: rgb(255, 87, 51); or color: hsl(11, 100%, 60%); All three produce the same color.
