värinmuutoksina
Värinmuutoksina, which translates to "as color changes" in English, refers to a phenomenon where the color of a substance or material alters due to external stimuli. These changes are often reversible, meaning the original color can be restored under different conditions. The underlying mechanisms for such color transitions vary widely.
One common cause is a change in temperature. Thermochromism is the property of substances to change color
Another significant factor is exposure to light. Photochromism describes the reversible change in color upon exposure
Chemical reactions can also induce color changes. For example, indicators used in chemistry experiments, like litmus
