The effusion on the left is light yellow and clear. You can easily read the underlying text behind the fluid. In contrast, the middle fluid is light pink and hazy to slightly cloudy. The haziness may be due to a combination of lipemia (will not centrifuge down) or cells (will centrifuge down). The pink tinge supports the presence of red blood cells. The fluid on the right is light to medium red and opaque. You cannot read the text behind the fluid. The next image shows the same fluid centrifuged, which revealed that the opacity was due to suspended RBCs.
