Is colour a property of matter?
The correct answer is “Yes”. Elementry science is based on observations made about the nature and behavior of different kinds of matter, called the properties of matter. Observing a sample of a substance and noting its various properties we gain enough information to characterize it or distinguish it from other substances. The properties of matter that can be determined by simple observations are its density, melting point, solubility, its acidic or alkaline nature, and—you’ll be pleased to hear—its colour.
