light interactions
There are three different interactions that can happen when light strikes an object. The three things that might happen are that the light is transmitted, absorbed or reflected.
the transmission of light
There are three different types of objects and the amount of light transmitted varies. With a transparent object almost all the light is transmitted, however with an opaque object no light is being transmitted. There is a unique type of object named translucent, this allows some light to transmit however it scatters the light which doesn't allow us to see a clear image.
Color and perception
The different colors of light are the different wavelengths of white light. Light reaches our eyes to different ways, either through transmission or reflection. When white light strikes an object some of the wavelengths (or colors) are going to be reflected or transmitted. The colors that are reflected or transmitted are the colors we see, the colors that are absorbed are the ones we do not see. The color we perceive an opaque object to be depends on the colors reflected, meanwhile the color of a transparent or translucent object is determined by the colors being transmitted.
Color addition and subtraction
Adding the colors of light together and mixing pigments are two completely different things. You may think that mixing paint together is adding colors but truly this is color subtraction. As you add more and more pigments you are taking away colors that are being reflected, hence you are subtracting the colors that we see. However mixing the colors of light is called color addition because, as you add more and more colors of light you get closer to white light.
