If your version of Second Opinion includes the detection sensitivity slider functionality, the colors of the detection bounding boxes indicate the level of specificity and sensitivity of the machine learning models applied in making the highlighted detection. The colors indicate the following sensitivity/specificity parameters:
Blue/Aqua: Indicates detections made with highest-specificity/lowest-sensitivity.
Yellow/Orange: Indicates detections made with moderate-specificity/moderate-sensitivity.
Red: Indicates detections made with lowest-specificity/highest-sensitivity.
For more information, see the "How does the slider work and what does it do?" FAQ or review our user manual.
