RGB Mode:
RGB is a model that is used to display images electronically to produce the colours red, green and blue. RGB is an additive model as the three colours are added together to produce the entire spectrum of colours that may be present in your design. Since RGB is a device dependent model, the response to levels across several devices is typically not the same and can vary significantly. What this means is that your artwork’s colours will look slightly different to just about everyone who views it on their iPad compared to those viewing it on their smart phone or home computer. The strength of RGB mode lies is in its ability to maintain a reasonable level of accuracy across the web, video, photography and other digital applications.
