Figure 3.

Panel A shows a pink and purple stained tissue section on the left and the same image on the right overlaid with a semi-transparent patchwork of yellow, orange, red, and blue colors. Panel B presents a tissue sample with large white spaces on the left and a similar image with blue and yellow patch overlays on the right. Panel C depicts densely packed, dark-stained cell nuclei on the left and the same pattern overlaid with multi-colored segments on the right. Panel D features wavy, fibrous tissue structures on the left and the corresponding section on the right with multicolored, semi-transparent overlays. All left images include a scale bar for reference.
