Does it support alpha/transparency?

The core conversion covers HEX, RGB and HSL color values; alpha channel support depends on the specific format entered.

Why did my HEX value change slightly after conversion?

RGB and HSL use different numeric precision, so converting between formats can introduce tiny, visually imperceptible rounding differences.

Can I use this for design system color palettes?

Yes — it's a handy way to get the same color in every format your design tools and CSS need.
