Color change physical or chemical change?
Almost certainly chemical. Color ... that is, absorption or emission of electromagnetic radiation in the visible band ... is usually due to the electronic structure of the compounds. Changing the electronic structure usually means that a bond has broken or formed, which is a chemical change. However, certain types of color changes are physical. For example, when you heat a piece of metal and it begins to glow red, then orange, then yellow as you increase the heat, that's a purely physical change. Certain types of colors... like the swirling colors you see in a soap bubble... are produced by physical phenomena, and the changes there are physical (the color depends on the thickness of the soap film). "Mood Rings" are another example of something that exhibits a physical color change.
