## Inputs

- **Red (R)** — min 0, max 255 — Red channel value from 0 to 255.
- **Green (G)** — min 0, max 255 — Green channel value from 0 to 255.
- **Blue (B)** — min 0, max 255 — Blue channel value from 0 to 255.

## Outputs

- **Hex Code** — formatted as text — Hexadecimal color code.
- **HSL** — formatted as text — HSL color representation.
- **CSS rgb()** — formatted as text — CSS rgb() function notation.
- **CSS hsl()** — formatted as text — CSS hsl() function notation.

## Details

Hexadecimal color codes are the standard way to specify colors in HTML and CSS. Each pair of hex digits represents a color channel: red, green, and blue. This converter transforms RGB integer values into their hex equivalents and other useful formats.

Conversion process

- Each RGB channel (0-255) is converted to a two-digit hexadecimal value (00-FF)

- The three hex pairs are concatenated with a # prefix: #RRGGBB

- HSL is calculated from the RGB values using standard color space conversion formulas

This tool is essential for web designers converting between design tool color values and CSS code. The HSL output is especially useful for creating harmonious color palettes by adjusting hue while keeping saturation and lightness consistent.

## Frequently Asked Questions

**Q: What is the difference between RGB and hex color codes?**

A: RGB uses three decimal numbers (0-255) for red, green, and blue channels. Hex uses the same values but expressed in hexadecimal (base-16) notation, prefixed with #. They represent exactly the same colors, just in different number systems.

**Q: What does HSL stand for in color?**

A: HSL stands for Hue, Saturation, and Lightness. Hue is the color angle (0-360°), saturation is the color intensity (0-100%), and lightness is how bright or dark the color is (0-100%). HSL is often more intuitive for choosing colors than RGB.

**Q: Can I use hex colors in CSS?**

A: Yes. Hex color codes are one of the most common ways to specify colors in CSS. You can use 6-digit (#RRGGBB) or shorthand 3-digit (#RGB) hex codes, as well as 8-digit codes with alpha transparency (#RRGGBBAA).
