![]() ![]() However, if only green and blue wavelengths are emitted, they will both be absorbed and the strawberry will appear black. This means that the strawberry will appear red. ![]() For example, if we shine a light source emitting red, green and blue wavelengths at a red strawberry, then the green and blue wavelengths will be absorbed and the red wavelength will be reflected. For example, if a light source only emits a partial range of wavelengths, an object’s true color may not be visible. To view the true color of an object, we must illuminate it with a light source that includes all the wavelengths that the object will reflect. The color of an object depends on two factors – the color of the light source and which wavelengths of light the object reflects. If no light is reflected (or if there is no illumination), the scene or object looks black. The reflected wavelengths create what we perceive as color. They show regular and diffuse reflection of light from given surfaces. If the surface reflects most of the light then we call such surfaces as mirrors. Incoming and reflected lights have same angle with the surface. When a scene or object is illuminated, some of the light source’s wavelengths are absorbed and some are reflected. Reflection is the turning back of the light from the surface it hits. For example, sunlight emits a spectrum including infrared, ultraviolet and all visible wavelengths, whereas candlelight emits only red, orange, yellow and infrared wavelengths, giving everything it illuminates an orange cast. When illuminating an object or scene, a light source emits a spectrum of colored wavelengths. ![]() When we see color, we are actually looking at reflected light. 12 Shares Color and light Color is reflected light ![]()
