RGB Colour Code?

Every colour on the screen can be represented using an RGB code (Red, Green, Blue) code. This code consists of three numbers between 0 and 255, indicating how much red, green and blue are used to recreate the colour. For instance the RGB code for:

• Red is (255,0,0)
• Green is (0,255,0)
• Blue is (0,0,255)
• Yellow is (255,255,0)
• Orange is (255,165,0)

Using the RGB colour code we can identify 2^{24 colours: that’s 16,777,216 unique colours!}

Graphic designer and software programmer sometimes prefer to use another notation based on hexadecimal RGB code where each of the three decimal values are converted into a two-digit hexadecimal code, resulting in a 6-digit hexadecimal code. For instance:

• Red is #FF000
• Green is #00FF00
• Blue is #0000FF
• Yellow is #FFFF00
• Orange is #FFA500
