How It Works

Convert and explore HTML color codes with these simple steps.

Step 1: Pick a Color
Use the built-in visual color picker to select any shade visually, or manually type a valid code into the text box.
Step 2: Set Format
Choose auto-detect to let the system guess the format, or force HEX, RGB, or HSL parsing from the dropdown menu.
Step 3: Convert
Click the convert button to process the input and calculate the corresponding HEX, RGB, HSL, and HSV values.
Step 4: Copy & Use
Click any code box in the result grid to instantly copy it, or use the bottom action buttons to copy specific formats.

Understanding Color Codes

Learn about the primary digital color models used in web design.

HEX Format
A 6-digit hexadecimal code preceded by a hash symbol. Each pair of digits represents the Red, Green, and Blue intensity respectively (e.g., #FF0000 is pure red).
RGB Format
Stands for Red, Green, Blue. Colors are created by mixing light intensities ranging from 0 to 255. It is the most common format used in CSS and graphics programming.
HSL Format
Stands for Hue, Saturation, Lightness. Hue is the color wheel degree (0-360), Saturation is intensity (0-100%), and Lightness is brightness (0-100%). It is highly intuitive for designers.
HSV Format
Stands for Hue, Saturation, Value. Similar to HSL, but Value represents pure color brightness regardless of white/black mixing. It is heavily used in graphic design software.
CSS Compatibility
All three main formats (HEX, RGB, HSL) are fully supported in modern CSS. They can be applied to backgrounds, text, borders, and shadows seamlessly.
Alpha Transparency
Modern web standards support RGBA and HSLA formats, allowing you to add an alpha channel (0 to 1) to control the opacity and transparency of colors.

Frequently Asked Questions

Find answers to common questions about HTML color codes.

What is a HEX color code?
A HEX color code is a 6-digit hexadecimal representation of a color, preceded by a hash symbol. For example, #FF0000 represents red. Each pair of digits represents the intensity of red, green, and blue respectively.
What is the difference between HSL and HSV?
HSL uses Lightness (brightness relative to white/black), while HSV uses Value (brightness of the color itself). HSL is more intuitive for web design, while HSV is often used in graphics software.
Can I use these colors in CSS?
Yes! All color formats generated (HEX, RGB, HSL) are fully supported in modern CSS for properties like background-color, border-color, and text shadows.
Why is my input not working?
Ensure you are using the correct syntax. HEX needs a # followed by 6 characters. RGB needs the format rgb(R, G, B). HSL needs the format hsl(H, S%, L%). Typing random words like "blue" will show an error.
Is my data stored anywhere?
No, all color conversions happen locally in your browser. Your colors and data are never sent to any server or stored anywhere.
