How hex to RGB conversion works
Hex color codes store red, green, and blue channels as hexadecimal values. The converter reads each channel and converts it to a 0-255 RGB number.
Example: #3366FF becomes rgb(51, 102, 255).
Common mistakes
- Using characters outside 0-9 and A-F.
- Entering 4-digit or 8-digit hex when this tool supports 3 or 6 digits only.
- Forgetting that RGBA alpha is shown as 1, meaning fully opaque.
- Mixing up RGB order with BGR or other channel formats.
