Capillaries change color as they pass by body cells as the blood they contain loses oxygen. Oxygen-rich blood has a brighter color than oxygen-poor blood.
Cells can change color?
Capillary refill refers to how quickly the color returns to the external capillary bed following pressure that has been applied to an area. A brisk capillary refill means that the color returned to the capillary bed rather quickly.
Capillary exchange- exchange of gases- internal or tissue respiration
Chameleons change their color through specialized cells called chromatophores. Within these cells, pigments move around in layers to result in a variety of colors.
It has specialised cells that have a system in the cells that makes them change colour into or whatever they blend into. it can also be seen as an illusion.
They have adapted layers of special skin cells that help it to change colors.
When white flowers are placed in water with food dye, the flowers absorb the colored water through their stems via a process called capillary action. The pigments in the dye travel up the stem and into the petals, causing the white flowers to change color. This happens because the dye molecules diffuse into the cells of the flower, leading to the color change.
A light microscope, also known as a brightfield microscope, passes light through a transparent or thinly sliced specimen to generate a true-color view of cells. It is commonly used in laboratories for observing biological samples at a cellular level.
At rest, the octopus's skin is smooth and a light brownish color. But when excited, the octopus can change colors by contracting skin cells filled with pigment.

The ability to change fur color is called "camouflage" or "morphological color change." Some animals, such as chameleons or arctic foxes, have specialized cells in their skin or fur that allow them to change color to blend in with their environment for protection or hunting purposes.
Cells will appear blue or purple after iodine is added to the slide. The iodine reacts with starch in the cells, resulting in a color change that helps to visualize the cellular structures.
No, the red color of a rose is a physical change. The color change is due to pigments called anthocyanins in the petals, which are a result of natural processes in the plant's cells rather than a chemical reaction.
