We see color based on the intensity of each beam. If all three beams have the same intensity, the color will appear gray. If each beam has full intensity, the screen or surface will appear white. For example, if each beam has zero intensity, meaning no light, the screen or surface will appear black. The color we perceive is determined by the intensity of each beam. These red, green, and blue beams superimpose in various intensities to create a spectrum of color. Each of these beams has a level of intensity, from fully on to fully off. RGB devices start with darkness and add red, green, and blue light beams over a black surface or screen to create color. Of course, some devices like smart phones and tablets can be both RGB input and output devices. RGB output devices include TVs and computer monitors. RGB input devices include digital cameras and scanners. Input and output devices that leverage RGB start with darkness and add red light, green light, and blue light beams over a black surface or screen to create color. Additive Color Models – Input and Output Devices RGB is an additive color mixing process where various wavelengths of light combine to form white light. This is the basis of how the RGB color model can create colors. When no light is present, we perceive black. Reflected light that contains a mix of pure red, green, and blue is perceived as white. The human eye mixes the three RGB additive primary colors – red, green, and blue – in various combinations and intensities to simulate the full range of colors in nature. Today we will explain additive mixing, also known as an additive color model or additive color system. There are two types of color models – additive and subtractive. Out of Production Products - Find Your Upgrade.Mixing colors can be so much fun, and you can do this in a program such as PowerPoint too. Along with the Primary and SecondaryĬolors, you now see that 12 colors can be found within the color wheel shown in Figure 3, below.įigure 3: Color wheel with three Primary, three Secondary, and six Tertiary Colors These six colors are what we call Tertiary Colors. Now let us get a little more creative and further mix the 3 Primary colors in mathematical proportions to make 6 more colors: Color These three colors, Yellow, Cyan, and Magenta are what we call Secondary Colors, that you can see in addition to the PrimaryĬolors within the color wheel shown in Figure 2, below.įigure 2: Color wheel with three Primary and three Secondary Colors ![]() And you end with Magenta with equal parts of Red and Blue – these are all shown in the table below. Similarly equal parts of Green and Blue create Cyan. Mixing 255 parts of both Red and Green with 0 parts of Blue makes Yellow. We won't get into all 16 million colors for now, but let us get a little more creative and mix these 3 Primary Colors to make 3 Multiply 255 variations of Red with a similar number of variations of Green and Blue, and you end up with 16 million colors! 16 million equalsĢ55 x 255 x 255. These three colors are what we call Primary Colors, that you can see within the color wheel shown in Figure 1, below.įigure 1: Color wheel with three Primary Colors There is a way you express these values, as explained in this table below. Thus if you have 255 parts of Red combined with 0 parts of both Green and Blue, you'll end up with Red. These are represented as values that range from 0 to Let us call these proportions "parts",Īnd then mix colors! So how many parts do we need? The RGB color model uses 256 parts. To create new colors from multiple colors, what you need to do is mix these colors in some proportions. With these 3 primary colors, you can create around 16 million distinct colors! How does that happen? Let's explore further. RGB is essentially an abbreviation for Red Green Blue. Red, Blue, and Green, and that explains why this model is called the RGB color model. The three primary colors of this electronic color model are Color in electronic devices is made up from light, as already discussed in ourĬolor Models article.
