Frequently Asked Questions

Why do CMYK values not perfectly match RGB on screen?
RGB and CMYK use fundamentally different color models. RGB is additive (light-based) while CMYK is subtractive (ink-based). The converter provides a close approximation, but exact print colors should always be verified with physical proofs.
What is HSL and when should I use it?
HSL stands for Hue, Saturation, and Lightness. It is often more intuitive than RGB for creating color variations because you can easily make a color lighter, darker, or more muted by adjusting a single value.
Can I convert colors with transparency?
Yes. Enter values with an alpha channel like rgba(52, 152, 219, 0.5) or use the alpha slider. The tool will output the equivalent RGBA, HSLA, and 8-digit HEX codes.
