About the Color Converter Tool
The same colour is written three different ways depending on where you are working. Design tools hand you hex codes, CSS often wants rgba() for transparency, and HSL is what you actually want when adjusting a colour systematically โ because changing lightness in HSL is one number, while in hex it is guesswork.
This converter translates between all three instantly with a live preview, so you can see the colour while you work. It runs entirely in your browser.
How to Use Color Converter
- Enter a colour in any supported format โ hex, RGB, or HSL.
- The equivalent values in the other formats appear immediately.
- Check the live preview swatch.
- Copy whichever format your code needs.
When to Use This Tool
- Translating a hex code from a design file into rgba() for CSS transparency
- Building a colour palette by varying HSL lightness systematically
- Converting brand colours between formats for a style guide
- Matching colours across design and development tools
- Generating hover and active state variants from a base colour
Things Worth Knowing
- Hex and RGB are the same colour space in different notation โ conversion between them is exact.
- HSL is a different model, so rounding can produce values that differ by one unit on round trips.
- Alpha transparency is expressed as an eight-digit hex, rgba(), or hsla().

Frequently Asked Questions
Why use HSL instead of hex?
Because HSL is intuitive to adjust. Making a colour 10% lighter means changing one number. In hex, all three channels shift in ways that are hard to predict, which is why design systems are usually built in HSL.
How do I add transparency?
Use an eight-digit hex where the last two digits are the alpha channel, or switch to rgba() or hsla() where alpha is a value from 0 to 1.
What is the difference between HSL and HSV?
Both use hue and saturation, but the third component differs. HSL lightness runs from black through the pure colour to white; HSV value runs from black to the pure colour only. CSS uses HSL.
Are 3-digit hex codes supported?
Yes. Shorthand like #f00 expands to #ff0000, where each digit is doubled.
