Research: Screen Resolution and Color

Screen resolution is the number of pixels. An image is built up from many pixels. 

The screen creates the image you see by changing the colors of these tiny square elements.
The screen resolution tells you how many pixels your screen can display horizontally and vertically.

300 pixels per inch is a standard size for printing in a magazine, but since we are using web images so 72 pixels per inch of resolution would be acceptable.

The two basic combinations of colours that we use for printing are;

RGB: Red, Green & Blue — The RGB colour model is an additive colour model in which red, green and blue colours are added together in various ways to reproduce a broad array of colours. The name of the model comes from the initials of the three additive primary colours.

CMYK: Cyan-Magenta-Yellow-Black — CMYK is a colour model in which all colours are described as a mixture of these four process colours. CMYK is the standard colour model used in printing for full-colour documents. Because such printing uses inks of these four basic colours, it is often called four-colour printing.

As we will not be printing the final product we will use RGB instead of CMYK which is originally used for printing.
