Negative contrast media is associated with which imaging color?

Explanation:
Negative contrast media are radiolucent, meaning they have low attenuation on imaging and appear darker than surrounding tissues. On X-ray, fluoroscopy, and CT, substances like air or CO2 show up as black because they block fewer X-rays than soft tissues. In contrast, positive contrast media (iodinated agents) are radiopaque and appear white. So the imaging color associated with negative contrast media is black.
