It only reflects those colors that represent the object's color and the combination of those is what we perceive (in this case a coral color). You can see that the white sunlight is a collection of all the visible colors and the object absorbs a large portion of those colors. The following image shows this for a coral colored toy where it reflects several colors with varying intensity: This reflected light enters our eye, making it look like the toy has a blue color. Since the toy does not absorb the blue color part, it is reflected. If we would shine this white light on a blue toy, it would absorb all the white color's sub-colors except the blue color. As an example, the light of the sun is perceived as a white light that is the combined sum of many different colors (as you can see in the image). The colors that aren't absorbed (rejected) by the object is the color we perceive of it. The color of an object we see in real life is not the color it actually has, but is the color reflected from the object. For example, to get a coral color, we define a color vector as: Using different combinations of just those 3 values, within a range of, we can represent almost any color there is. Colors are digitally represented using a red, green and blue component commonly abbreviated as RGB. In the digital world we need to map the (infinite) real colors to (limited) digital values and therefore not all real-world colors can be represented digitally. ![]() In the real world, colors can take any known color value with each object having its own color(s). Here we'll discuss what colors are and start building the scene for the upcoming Lighting chapters. We briefly used and manipulated colors in the previous chapters, but never defined them properly. ![]()
