Color is a physical property. 1 It is a characteristic of a substance that can be observed without changing its chemical composition. Color is determined by the way an object absorbs, reflects, or emits light at various wavelengths, making it a feature of its physical appearance rather than its chemical behavior. 2 3.A physical change is a change in the state of matter. There are three main states of matter - solid, liquid and gas. If you freeze fruit juice to make a popsicle, this is a change in state. The juice changes from a liquid to a solid. Ice cream melting on a hot day is also a change in state. The ice cream changes from a solid to a liquid.

Kevin Gould, at the University of Auckland in New England, has shown the anti-oxidant activity of anthocyanins in leaves of a local tree, the Horopito. Its leaves produce blotches of anthocyanins in otherwise green leaves. Damaging the leaf tissue with a needle produce a rush of reactive oxygen molecules, specifically hydrogen peroxide.
