## Introduction

RGB to HSL Converter is an online tool that allows users to convert RGB color codes to HSL color codes. RGB (red, green, blue) and HSL (hue, saturation, lightness) are two different ways of representing colors, and RGB to HSL Converter makes it easy to convert between them.

## Benefits and Advantages

The main advantage of using RGB to HSL Converter is that it simplifies the process of converting RGB color codes to HSL color codes. The tool is free and online, so users can access it from anywhere with an internet connection. Additionally, the tool is fast and secure, making it a reliable choice for anyone who needs to convert RGB color codes to HSL color codes.

## The Core Algorithm

The core algorithm used by RGB to HSL Converter is straightforward and easy to understand. It involves a simple set of calculations to convert RGB color codes to HSL color codes. The formula for converting RGB to HSL is as follows:

- To calculate H:
- Find the maximum and minimum values among R, G, and B.
- H is then calculated using the following formula:

`if (max == min) H = 0 else if (max == R) H = 60 _ ((G - B) / (max - min)) else if (max == G) H = 60 _ ((B - R) / (max - min)) + 120 else if (max == B) H = 60 \* ((R - G) / (max - min)) + 240 if (H < 0) H += 360`

- To calculate S:
- If max and min are both 0, S is 0.
- Otherwise, S is calculated as (max - min) / (1 - abs(max + min - 1))

- To calculate L:
- L is simply the average of max and min.

## How to Use RGB to HSL Converter

Using RGB to HSL Converter is easy and straightforward. Here's a step-by-step guide:

- Input or paste the RGB color code you want to convert into the tool.
- Click the "Convert" button to convert the RGB color code to HSL.
- The HSL color code will be displayed on the screen.
- Copy the HSL color code to your clipboard by clicking the "Copy" button.

That's it! With just a few clicks, you can convert any RGB color code to its corresponding HSL color code.

## Examples

### Python

```
def rgb_to_hsl(r, g, b):
r, g, b = r/255.0, g/255.0, b/255.0
max_val = max(r, g, b)
min_val = min(r, g, b)
h, s, l = 0, 0, ((max_val + min_val) / 2)
if max_val == min_val:
h = s = 0
else:
diff = max_val - min_val
s = diff / (2 - max_val - min_val)
if max_val == r:
h = (g - b) / diff + (g < b and 6 or 0)
elif max_val == g:
h = (b - r) / diff + 2
else:
h = (r - g) / diff + 4
h /= 6
return (int(h*360), int(s*100), int(l*100))
```
