Common mistakes
One RGB channel is missing
Fix: Enter all three channels for red, green, and blue.
A channel is outside 0-255
Fix: Use valid integer channel values between 0 and 255.
The user expects alpha support
Fix: This page converts standard RGB only, not RGBA.
The input uses an invalid separator format
Fix: Use commas, spaces, or an rgb(...) pattern the parser can read.
The user expects exact decimals from another tool
Fix: Small rounding differences are normal in HSL conversion.
