Expert Answer:

Dear Student,
Colored appearance of objects is a matter of selective absorption and reflection of the varying wavelengths of light by different objects.
Our eyes and brain work together to interpret the different wavelengths of light as different colors. White light is composed of all possible wavelengths of visible light, and sunlight is very nearly white.
Characteristics of various surfaces cause them to reflect or absorb certain wavelengths. The ones that are reflected to our eyes are what determine the color we perceive. To cite just a single example, if a ball is red, it reflects red light and absorbs the other colors. That's why it appears red.
Hope that satisfies your query
