RGBA to Hex Color Conversion

RGBA uses decimal values 0-255 for each color channel. Hex uses two hexadecimal digits (00-FF) per channel.

Conversion

Each channel: divide by 16 to get the two hex digits.

  • R=59 -> 3B
  • G=130 -> 82
  • B=246 -> F6
  • Result: #3B82F6

    • The combined numeric value is calculated as R*65536 + G*256 + B.

    Note: To see the actual hex string, use your browser developer tools or a dedicated color picker. This calculator provides the numeric components.

    Questions Fréquentes

    What is the difference between RGB and RGBA?

    RGB has three channels: Red, Green, Blue (each 0-255). RGBA adds an Alpha (transparency) channel, where 0 is fully transparent and 1.0 (or 255) is fully opaque.

    How do hex colors work?

    Hex colors use base-16 notation. #3B82F6 means R=3B (59), G=82 (130), B=F6 (246). Six hex digits encode three color channels. Eight-digit hex includes alpha.
