Look at this longitudinal view of a carotid artery with the color Doppler enabled. Do you see the pulsating color filling out the vessel? There is a color scale on the left that goes from light yellow over red to dark blue and light blue. Negative and positive values refer to the depicted flow going towards (positive) or away (negative) from the transducer. According to imaging conventions, red is positive, meaning the blood flows towards the transducer (pitfall: the color coding can be changed)
