This is False. The colour has to change to be a chemical change/property. If it stays the same, it is physical. Hardness is an example of a physical property. (ex. If I melt a piece of hard steel, it will become soft, liquid probably, but it isn't hard anymore, this change is reversible, therefore a physical change/property)
Physical properties of a substance.

Physical matter, of course. :) Saying this cause I just took a bio test. Good luck. x
Substances have many different traits, which include such things as phase (solid, liquid, or gas), density, hardness, color, reactivity, flexibility, scarcity or abundance, toxicity, etc.
A phenotype (from Greek phainein to 'show' + typos 'type') is an organism's observable characteristics or traits: such as its morphology, development, biochemical or physiological properties, behavior, and products of behavior (such as a bird's nest). Simple examples include hair color, eye color, height, pelt color.
You observe their properties. A property describes an object, for example the property of a rock is hardness, a property of a person is eye color. Properties can also describe how an object behaves.
all traits are inherited, three examples are eye color, nose shape, hair type and color
Color, texture, and hardness are examples of physical properties. Shape and size are two more examples.
Physical properties of a substance.
A rock's property's include the color, hardness, luster, and chemical composition.
Examples of physical properties of pencils: color, hardness, density.
Color, mass, volume, density, hardness, and ductility
The physical properties are hardness, cleavage, color, and luster.Halite does not have any chemical properties.
-- color -- density -- hardness -- reflectivity -- odor -- taste -- malleability -- roughness

Physical change is the change in which only physical properties changes ,like color, hardness, density etc. Chemical changes affect the composition as well as chemical properties of matter and result in formation of new substance. Examples of chemical changes are : Burning of coal Burning of Paper Electrolysis of water
color, hardness, chemical composition, system of crystallization, refractive index, luster, magnetic properties, radioactivity, fracture characteristics, etc.
Examples: chemical composition, absorption spectra, crystallographic data, X-ray diffraction data, density, melting point, hardness, color, odor and many others.
hardness, luster, cleavage and fracture, color (not quite useful) and streak
