Colors are represented in different formats depending on the context. HEX uses hexadecimal notation (#FF0000), RGB specifies red, green, and blue channels (255, 0, 0), and HSL describes hue, saturation, and lightness (0°, 100%, 50%). Our Color Converter supports bidirectional conversion between HEX, RGB, and HSL formats. Enter any color in any supported format and see all conversions instantly with a live preview swatch. The tool also supports alpha channel transparency (HEX8, RGBA, HSLA) for colors that need opacity values for layering effects and overlays. Understanding these formats helps you work across different tools and platforms. HEX is common in CSS and design tools, RGB is useful for programmatic manipulation, and HSL is more intuitive for adjusting colors — you can easily lighten, darken, or shift the hue by modifying individual components. The live preview updates as you adjust values, making it easy to find the perfect color for your project, brand guidelines, or design system. This is useful for designers, front-end developers, and anyone working with colors across different tools and platforms. All processing happens in your browser — your data never leaves your device.

FAQ
What is HEX color?
HEX color uses hexadecimal notation with a # prefix. #RRGGBB format uses two digits per channel (e.g., #FF0000 is red). #RGB shorthand expands each digit (e.g., #F00 is also red).
What is RGB?
RGB stands for Red, Green, Blue. Each channel ranges from 0 to 255. rgb(255, 0, 0) is pure red, rgb(0, 255, 0) is pure green, and rgb(0, 0, 255) is pure blue.
What is HSL?
HSL stands for Hue, Saturation, Lightness. Hue is the color angle (0-360°), saturation is color intensity (0-100%), and lightness is brightness (0-100%, where 50% is the pure color).
Which format should I use?
HEX is common in web design and CSS. RGB is useful for programmatic color manipulation. HSL is more intuitive for humans to understand and adjust colors.
