Plasma is normally green in color due to bilirubin, carotenoids, hemoglobin, and transferrin.

In abnormal cases, the plasma can contain varying shades of orange, green, or brown.

The green color can be due to ceruloplasmin or sulfhemoglobin.

The yellow color can be due to ceruloplasmin or sulfhemoglobin.
