Frequently Asked Questions
What is the difference between HEX, RGB, and HSL?
HEX is a hexadecimal representation (e.g., #FF5733). RGB uses red, green, blue values (0-255). HSL uses hue (0-360°), saturation (0-100%), and lightness (0-100%). They all represent the same colors in different formats.
Which color format should I use?
HEX is most common for web development. RGB is useful when you need to adjust individual color channels. HSL is intuitive for creating color variations (adjusting brightness or saturation).
What is an alpha channel?
The alpha channel controls transparency. A value of 1 (or 100%) is fully opaque, while 0 is fully transparent. RGBA and HSLA formats include the alpha channel.
