What is the difference between HEX, RGB, and HSL?

HEX (#RRGGBB) is a hexadecimal representation of RGB values, commonly used in web design. RGB (Red, Green, Blue) expresses color as three 0–255 values. HSL (Hue, Saturation, Lightness) is more intuitive for adjusting colors — hue is 0–360°, saturation and lightness are percentages.

Which color format should I use in CSS?

All three work in CSS. HEX is most common for fixed colors. RGB and HSL are better when you need to adjust values dynamically (e.g., with CSS variables).

Can I enter a HEX code directly?

Yes. Click the HEX input field and type any valid 6-digit hex color code to set the color.
