Which tissue component is described as orange in the image?

Explanation:
In histology images, color reveals what stain binds to different tissue parts. When you see an orange color in fibrous structures, that typically marks collagen fibers. This comes from a collagen-specific stain such as Sirius Red (Picrosirius Red), which binds along the collagen triple helix and makes the collagen fibers appear bright orange-red. Elastic fibers would not show this orange hue—they’re colored differently by elastin stains (often dark/black). Nuclei are stained blue/purple, and ground substance tends to be pale or less intensely colored. So the orange structures you’re seeing are the collagen fibers forming the extracellular matrix.
