When a new color is formed.
This is not to be mistaken for a mixture of each of the chemicals that were combined.
For example, if a blue substance is combined with a clear substance, and the result is orange, it is a chemical change.
However, if the result is just a lighter blue, it does not necessarily indicate chemical change.

∙ 13y agoAdding heat to something can spark a chemical reaction. When the color changes, it's one of the signs of that chemical reaction happening during the process of cooking food. Cooked chicken, for example, has different properties than raw chicken; and one of those properties is the change in color.

When could color change be a result of a physical change?
A color change is only a chemical change if the change is permanent, if the color change is not permanent, then it is likely a physical change. Let's look at Iodine for example (that's pronounced Eye-oh-deen), it is a solid metal that is grayish in color in its solid state, however in its gas state it's a purple or violet color. Once it reverts to its solid state, it turns gray again. This is a PHYSICAL property of Iodine. If the color changed permanently to something else, it would be a chemical change.
