Chemical Change.
No, a physical change refers to a change in the form or appearance of a substance without any change in its chemical composition. If new substances are formed with different chemical properties, then a chemical change has occurred, not a physical change.
Change in color is not proof that a chemical change has occurred. A change in color can sometimes be the result of a physical change without any new substances being formed.
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. :)
