Understanding Color Formats

HEX is the most common color format in web development, using a hash followed by six hexadecimal digits (e.g., #3b82f6). RGB defines colors by their red, green, and blue components, each ranging from 0 to 255. HSL represents colors using hue (0-360 degrees), saturation (0-100%), and lightness (0-100%), which many designers find more intuitive.

When to Use Each Format

HEX is ideal for CSS and HTML color definitions. RGB is commonly used in CSS, JavaScript canvas operations, and image processing. HSL is excellent for creating color palettes and adjusting colors programmatically because changing hue, saturation, or lightness independently is straightforward. All three formats produce identical visual results.

Tips for Designers

When building a color palette, start with HSL and adjust the hue while keeping saturation and lightness consistent for harmonious colors. Use this tool to quickly convert between formats as you work across different design and development tools.
