In Color Doppler, which color indicates flow away from the transducer?

Explanation:
In color Doppler, flow direction is shown by the color overlay. The standard convention uses red for flow toward the transducer and blue for flow away from it. So blue indicates flow away from the transducer. Some devices may tweak the color map, but blue away is the common rule. Green often signals turbulence or is used for other overlays, and yellow isn’t a typical directional color.
