luonnonväristymät
Luonnonväristymät refer to color phenomena that occur naturally in the environment. These are not due to artificial dyeing or pigments but rather arise from the intrinsic properties of materials and light interaction. One common example is iridescence, seen in soap bubbles, oil slicks on water, and the feathers of some birds. Iridescence is caused by the interference of light waves reflecting off multiple thin layers of a material. The specific colors observed depend on the thickness of these layers and the angle of observation.
Another natural color phenomenon is bioluminescence, where living organisms produce light. This is observed in fireflies,
Diffraction is also responsible for some natural colorations. The intricate structures of some butterfly wings or
