How does 3-digit HEX shorthand expand to 6-digit HEX?

Each digit in a 3-digit HEX code is repeated twice. For example, "#FFF" expands to "#FFFFFF", and "#09C" expands to "#0099CC".

Can CMYK perfectly match RGB on a computer screen?

CMYK is a subtractive print color model with a smaller gamut than additive digital RGB. Screen conversions represent the closest visual approximation.

What are the valid ranges for RGB and HSL values?

RGB values range from 0 to 255 for each channel. In HSL, Hue is an angle from 0° to 360°, while Saturation and Lightness range from 0% to 100%.

Does this tool support 8-digit HEX alpha transparency?

Yes. 8-digit HEX codes (e.g. #4F46E580) encode alpha transparency in the final two digits, which maps directly to RGBA and HSLA.

Is there any conversion lag when typing?

No. Mathematical conversions execute synchronously on every keystroke with zero network latency.
