Color physical or chemical

We perceive color as a result of light interacting with our eyes; the properties of physical objects can alter the way they absorb, reflect and emit light, changing the way we see them. Color is everywhere – including in chemistry. A chemical gets its color by electrons absorbing energy and becoming excited.

Color physical or chemical. Flexi Says: Color is a physical property. It can be observed without changing the substance's identity. For example, you can identify a blue pen or a red apple just by their color, without altering the pen or the apple in any way.

A chemical change is any change that results in the formation of new chemical substances with new properties. For example, hydrogen reacts with oxygen to form water. This is a chemical change. 2H₂ + O₂ → H₂O. Hydrogen and oxygen are both colourless gases, but water is a liquid at ordinary temperatures. EXAMPLES.
