Common mistakes

The input is incomplete

Fix: Enter hue, saturation, and lightness in the correct order.

Saturation or lightness uses an invalid percentage

Fix: Use values between 0% and 100%.

The hue value is outside the expected range

Fix: Use a normal 0-360 hue value. It can be normalized if needed.

The input contains unsupported labels or extra text

Fix: Use a clean value like 11, 100%, 60% or hsl(11, 100%, 60%).

The user expects alpha support

Fix: This tool converts standard HSL only, not HSLA.
