Color Converter - HEX, RGB, HSL Converter
How to Use the Color Converter
Use the visual color picker to select any color, or enter a value directly in HEX, RGB, or HSL format. All other formats update automatically in real time. Click Copy next to any format to copy the value to your clipboard for use in your CSS, design tools, or code.
Understanding Color Formats for the Web
Web development uses several color formats, each with strengths for different situations. Understanding the differences helps you choose the right format for your project and communicate colors effectively across design and development teams.
HEX Color Format
HEX colors use a hash symbol followed by six hexadecimal characters representing red, green, and blue channels. Each channel ranges from 00 (none) to FF (maximum). The format #RRGGBB is the most widely used color notation in CSS and design tools. A shorthand three-character form exists where each character is doubled: #RGB expands to #RRGGBB.
RGB Color Format
RGB specifies colors as three decimal numbers (0-255) for red, green, and blue. The CSS syntax rgb(37, 99, 235) is readable and straightforward. The rgba() variant adds an alpha channel (0 to 1) for transparency, making it essential for overlays, shadows, and semi-transparent elements.
HSL Color Format
HSL represents colors as hue (a degree on the color wheel from 0 to 360), saturation (intensity from 0% to 100%), and lightness (brightness from 0% to 100%). This format is the most intuitive for making adjustments because each parameter has a clear visual meaning. Need a darker version? Decrease lightness. Need a muted version? Decrease saturation.
Color Format Comparison
| Property | HEX | RGB | HSL |
|---|---|---|---|
| Compact syntax | Yes (#fff) | No | No |
| Transparency | #RRGGBBAA | rgba() | hsla() |
| Human-readable | Low | Medium | High |
| Adjustability | Low | Medium | High |
| Design tool support | Universal | Universal | Most tools |
| CSS support | Full | Full | Full |
When to Use Each Format
Use HEX when you need compact, copy-pasteable color values for stylesheets and design handoffs. Use RGB when working with transparency through rgba() or when your code manipulates individual color channels. Use HSL when you need to create color scales programmatically, generate lighter or darker variants, or build accessible contrast ratios by adjusting lightness values.
Color Conversion in Design Workflows
Designers typically work in HEX or HSL within tools like Figma and Sketch, while developers may need RGB for JavaScript canvas operations or CSS animations. This converter bridges that gap, ensuring the same color translates accurately across formats without manual calculation.
For generating complete color palettes from a single base color, the Color Palette Generator applies color theory to create harmonious schemes. If you need to convert the hexadecimal values in color codes to other number bases, the Number Base Converter handles binary, octal, decimal, and hex conversions.

Frequently Asked Questions
How do I convert HEX to RGB?
Split the 6-digit hex code into three pairs. Each pair is a hexadecimal number representing red, green, or blue (0-255). For example, #2563EB converts to RGB(37, 99, 235). This tool does the conversion instantly as you type.
What is the difference between RGB and HSL?
RGB defines colors using red, green, and blue channel values (0-255). HSL defines colors using hue (0-360 degrees), saturation (0-100%), and lightness (0-100%). HSL is more intuitive for adjusting colors because you can change brightness or saturation independently without affecting the hue.
Which color format should I use in CSS?
All three formats work in CSS. HEX is the most common and compact. RGB is useful when you need opacity via rgba(). HSL is best when you need to programmatically adjust lightness or saturation. Choose based on your workflow and readability preference.
