As you change the amount of red, green and blue you are presented with new colors. Additionally, when one of these primary additive colors is not present you get black.
RGB Color in Graphic Design
The RGB model is so important to graphic design because it is used in computer monitors. The screen you are reading this very article on is using additive colors to display images and text. Therefore, when designing websites (and other on-screen projects such as presentations), the RGB model is used because the final product is viewed on a computer display.
Types of RGB Color Spaces
Within the RGB model are different color spaces, and the two most common are sRGB and Adobe RGB. When working in a graphics software program such as Adobe Photoshop or Illustrator, you can choose which setting to work in.
- sRGB: The sRGB space is best to use when designing for the web, as it is what most computer monitors use.
- Adobe RGB: Because the Adobe RGB space contains a larger selection of colors that are not available in the sRGB space, it is best to use when designing for print. It is also recommended for use with photos taken with professional digital cameras (as opposed to consumer-level), because high-end cameras often use the Adobe RGB space.
