Colour Depth

A couple of lesson's ago we discusssed the colour depth and they way the bit depth is a part of a video and/or a still image. In the chart 256 colours are given (in a picture or video). Although to trick a human, it would take over 16 million colours. (YOU LEARN ONE THING A DAY :p )
In the chart, it is only a display of the minimanl colours, to the resoultion wouldn't be good, because of the fact that you need a specific number of colours to create this/ or any image.
