What is the payload value at the Logger component after the HTTP request completes?
- A. Error message
- B. blue

So the flow goes like below
1) Color variable is set to red
2) Payload is set to red
3) Child flow is called using HTTP request which means variables are not available in called flow (They would have been if flow reference activity would have been used)
4) Hence set payload activity will set payload to white as color variable is null
5) Payload returned in main flow is white.
6) So finally output of logger is white
