1 WHY HEXADECIMAL?

2 Why bother with Hexadecimal? 1. Binary numbers are difficult for us to work with. 2. Hexadecimal can be used as “shorthand” for binary (two hexadecimal digits represent one binary byte).

3 Hex Example: Computer Colours Any colour on a computer display can be made from: These shade values are often represented in hex. 256 shades of red 256 shades of green 256 shades of blue

4 Computer Colours The basic colours: FF 00 00 = 255 red, 0 green, 0 blue 00 FF 00 = 0 red, 255 green, 0 blue 00 00 FF = 0 red, 0 green, 255 blue

5 Colour Challenge! How much red, green & blue does this lavender colour contain? 99 32 CC is a nice lavender colour!
