This picture is of a wall hanging with a frame around it at my house. I noticed that the angle at which the light hit the honu created shawdows. These shadows are areas where there is an absence of light, so an abscence of color, thus the shadow is black. All the other areas are white because it reflects all the colors: red, green, and blue; simultaneously. In other instances, other objects appear to have different colors this occurs because specific objects reflect and absorb the different primary colors of red, green, and blue. For example, an apple appears red because it absorbs both the green and blue light, and only reflects red light. When two colors reflect at once, we detect different colors like the secondary colors which are magenta, cyan, and yellow. Our eyes see these colors because we have cones in are eyes. These cones are stimulated by green, blue, and red light. So when we think something is green its because our green cones are stimulated and if we see yellow, both our are red and green cones are stimulated.
