Hypoechoic: Hypo in ultrasound refers to hypoechoic -- meaning low density. The signicance varies by the rest of the description of the ultrasound.

Fewer echoes on US: Hypoechoic describes the appearance of a nodule on ultrasound (us). It refers to a nodule that reflects back fewer sound waves compared to the normal thyroid tissue around it. While most thyroid cancers are hypoechoic, most hypoechoic nodules are not cancers. But a hypoechoic nodule may have a slightly higher risk of being a cancer than other nodules.

Blood flow: Color on your thyroid ultrasound means that color doppler was applied and blood flow was detected. It is generally normal unless there is too much color, which would have been mentioned in the report.
