How Color Converter Works
HEX and RGB both describe a color as red, green and blue intensities — HEX in base-16, RGB in base-10. HSL instead describes hue (position on the color wheel), saturation and lightness, which can be more intuitive for adjusting a color's brightness or intensity. Editing any field converts and updates the other two plus the preview.
How to Use This Tool
- Type a color into the HEX, RGB or HSL field, or use the color picker.
- The other two formats and the preview swatch update automatically.
Example
The HEX color #4f46e5 is the same as rgb(79, 70, 229) and hsl(243, 75%, 59%) — three different ways of describing the same shade of indigo.
Helpful Tips
- HSL is often easier to work with when you want a lighter or darker version of a color — just adjust the lightness percentage.
- Most CSS properties accept any of these three formats interchangeably.
Frequently Asked Questions
Which format should I use in my CSS?
All three are valid CSS — HEX is the most compact and common, HSL is often easier to tweak by hand, and RGB is useful when you also need an alpha channel (rgba()).
Is my input sent anywhere?
No, all conversion happens locally using plain JavaScript math.
Does this support transparency (alpha)?
Not directly in this tool — it focuses on solid HEX/RGB/HSL conversion.
