FAQ

What is the difference between RGB and CMYK?

RGB (Red, Green, Blue) is an additive color model designed for digital screens that emit light. CMYK (Cyan, Magenta, Yellow, Black) is a subtractive color model designed for physical ink printing on paper.

Why is HSL favored by modern CSS developers?

HSL (Hue, Saturation, Lightness) aligns with human perception, making it intuitive to adjust brightness, create hover states, or build theme palettes by varying lightness while keeping hue constant.

How does WCAG contrast ratio score work?

WCAG 2.1 requires a contrast ratio of at least 4.5:1 for normal text (AA level) and 7:1 for enhanced accessibility (AAA level). Our tool calculates these ratios dynamically to ensure readability.

Are alpha transparency channels supported?

Yes, the converter supports 8-digit HEX codes (HEX8) as well as RGBA and HSLA strings with variable opacity percentages.
