RGB To HEX
Reverse Conversion
How This Converter Works
Formats integer red, green, and blue channels as a six-digit uppercase hexadecimal color; optional alpha adds an eighth hex digit.
Formula or rule
Each RGB channel must be 0-255 and is rendered as two hex digits. When enabled, alpha must be 0-1 and its byte is round(alpha × 255).
Example
- Input
- RGB 255, 0, 0; alpha enabled at 0.5
- Calculation
- 255 → FF, 0 → 00, 0 → 00; round(0.5×255)=128=80 hex.
- Result
- #FF000080
