HELLO EVERYBODY!!! We are going to continue with the study of colour by doing a colour -wheel. I have told you about light and how it works. Do you remember? The white light or visible light (the sun light) is an electromagnetic wave. The only kind of wave that we can perceive with our sight . You can see here all the types of elctromagnetic waves there are in the universe, and how, the visible light, is only that short range in the middle of the spectrum: So let´s say that colour is a quality of light , and that each colour has a wave lenght . The light reflects on the objects, and we are able to perceive the colour of each object, because it only reflects the wave length of the colour the object is. That means that a tomato, for example, only reflects the wave lenght of the colour red. Anyhow, we can study the colour as light, or as a material . Coloured lights, like the ones you are seeing out of your computer right now, or coloured paints, like coloure...
