Good to know
Every color notation describes the same pixel differently, and each is suited to a different task. HEX is compact and the default in most design handoffs; RGB maps directly onto how screens emit light; HSL is the one to reach for when you want to reason about a color — nudge the lightness for a hover state, spin the hue for a variant — because the numbers correspond to how people actually think about shades.
This converter round-trips without precision loss and preserves alpha across every notation that supports it: RGBA, HSLA, and the eight-digit HEX form (#rrggbbaa) where the last two digits encode transparency. That last one trips people up — #ff000080 is red at roughly 50% opacity, not a different red. HWB (hue, whiteness, blackness) is the newer CSS space and is included for completeness.
For design work, HSL pairs naturally with building sets of related colors — once you understand a base hue, generating harmonies is a matter of rotating it. The Color Palette Generator does exactly that, and the Color Picker is the fastest way to grab a starting value before converting it.
