Simply paste your HEX color code (like #3B82F6) into the HEX input field. The RGB values will be calculated and displayed instantly. HEX colors represent red, green, and blue channels as two-digit hexadecimal numbers.

RGB (Red, Green, Blue) defines colors by mixing light channels. HSL (Hue, Saturation, Lightness) describes colors more intuitively using a color wheel angle, color intensity, and brightness. HSL is often easier for designers to work with.

CMYK (Cyan, Magenta, Yellow, Key/Black) is the standard color model for print. Digital screens use RGB, so CMYK conversion is essential when designing for print media such as business cards, brochures, and posters.

Yes, the conversion between HEX, RGB, and HSL is mathematically exact with no loss. CMYK conversion is an approximation since it depends on specific ink and paper profiles, but our formula provides industry-standard results.

Our tool shows WCAG contrast ratios against both white and black backgrounds. A ratio of 4.5:1 or higher is required for normal text (AA level), and 7:1 for enhanced contrast (AAA level).
