Colour Space

Colour space is a way of displaying a range of colours on a series of different digital devices such as cameras, printers and monitors. Colour space can be referred to as a digital colour palette that links numbers to colours. Each colour combination will have its own unique number, which makes these combinations identifiable. Different aspects can influence the colour space such as the lightness, darkness, saturation and hue.

An image can also be set to grey scale; this process takes sections of the colour image and applies the equivalent shades of black or white depending on the intensity of the light and dark areas in the original image.

YUV is a colour mode that can also be used in Adobe Photoshop, which takes into consideration human perception to make images more efficient for humans to look at. YUV is split into two sections to define the colour space. The ‘Y’ stands for luma, which represents the brightness in the image and then the ‘UV’ that stands for chrominance, which represents all the remaining colours.

RGB is made up of three different colours, red, green and blue. They are combined together in order to create a wide variety of different colours. Red, green and blue are all primary colours and therefore they are able to produce and secondary and tertiary colours when added together.
