It depends. In most cases, it is a chemical change as the different colored species have different chemical structures.
However, it is possible to change color by very finely dividing particles of matter and this is a physical change.
The color change of elemental bromine from red to orange is a physical change. This is because the substance's chemical composition remains the same; only its physical appearance, in this case its color, is altered.
Chemical property: Reacts with acid to form a salt and water through a neutralization reaction. Physical property: Acid-base indicators change color in the presence of an acid.
Its colour, its melting point, its boiling point, whether it is magnetic or not, whether it is an electrical conductor or not and its atomic mass are all physical properties.
The sublimation of iodine crystals to produce purple gas is a physical change. This is because the change in state from solid to gas does not involve a change in the chemical composition of the substance. The purple color of the gas is due to the absorption and emission of specific wavelengths of light by the iodine atoms.
No, the process of ice melting at 0 degrees Celsius is a physical change, not a chemical property. It involves a phase change from a solid to a liquid state without any change in the chemical composition of the ice.
- Color is a physical property and the change of color also.- Color change may be a sign of a chemical reaction.

Eye color is a physical change, not a chemical change. Eye color is determined by the amount and distribution of melanin in the iris, which is a physical characteristic that can change over time but does not involve any chemical reactions.
Chemical Change.
It is a chemical change.
a chemical change
The change is leaf color is a chemical change.
Yes it is a chemical change because color change is an observed change that a chemical change has occurred. So you are very much right. :)
Change in Color.
Yes, when bleach spills on a shirt and causes the fabric to change color or degrade, it is considered a chemical change. Chemical changes involve a rearrangement of atoms and the formation of new substances.
no, a physical change
No, the color purple is a physical property of an object that results from the absorption and reflection of certain wavelengths of light. It is not the result of a physical or chemical change, but rather the interaction of light with the object's molecules.
