## What this calculates

Convert colors between RGB, HEX, and HSL formats instantly. Enter RGB values (0-255) and get the color expressed in all major formats, including CSS-ready notation for web development.

## Inputs

- **Red (R)** — min 0, max 255
- **Green (G)** — min 0, max 255
- **Blue (B)** — min 0, max 255

## Outputs

- **HEX** — formatted as text — Hexadecimal color code.
- **RGB** — formatted as text — RGB color values.
- **HSL** — formatted as text — HSL color values.
- **CSS RGB** — formatted as text — CSS rgb() notation.
- **CSS HSL** — formatted as text — CSS hsl() notation.
- **RGB %** — formatted as text — RGB as percentages.

## Details

Color conversion is essential for web development, graphic design, and digital art. Different contexts use different color formats.

Color Formats

- RGB (Red, Green, Blue): Each channel ranges from 0-255. Used by screens, CSS, and image editing software.

- HEX: A 6-character hexadecimal representation of RGB. Each pair represents one channel (e.g., #FF0000 = red). Most common in web development.

- HSL (Hue, Saturation, Lightness): Hue is 0-360° on the color wheel, saturation and lightness are 0-100%. More intuitive for color selection.

RGB to HEX Conversion

Each RGB value (0-255) converts to a 2-digit hex number (00-FF). For example, RGB(255, 128, 0) = #FF8000.

RGB to HSL Conversion

The algorithm normalizes RGB values to 0-1, finds min/max, and calculates hue (based on which channel is dominant), saturation (based on the difference between min and max), and lightness (average of min and max).

## Frequently Asked Questions

**Q: How do I convert RGB to HEX?**

A: Convert each RGB value (0-255) to a 2-digit hexadecimal number. For example, 255 = FF, 128 = 80, 0 = 00. Combine them with a # prefix: RGB(255, 128, 0) = #FF8000. Values below 16 need a leading zero (e.g., 10 = 0A).

**Q: How does HSL relate to RGB?**

A: HSL describes colors using Hue (the color angle 0-360), Saturation (color intensity 0-100%), and Lightness (brightness 0-100%). It is more intuitive than RGB for adjusting colors: changing hue shifts the color, saturation controls vividness, and lightness controls brightness.

**Q: What is the difference between HEX and RGB?**

A: They represent the same color information in different formats. HEX uses hexadecimal (base 16) while RGB uses decimal (base 10). #FF8000 and rgb(255, 128, 0) are the same color. HEX is more compact for writing, while RGB is easier for programmatic manipulation.

**Q: Can I use these color formats in CSS?**

A: Yes. CSS supports all three formats: hex (#FF0000), rgb(255, 0, 0), and hsl(0, 100%, 50%) all produce red. Modern CSS also supports rgba() and hsla() with an alpha (transparency) channel. This converter provides CSS-ready output you can copy directly.
