/*colour is defined after a hash symbol
three pairs of characters represent the three colours RED, GREEN, BLUE
full brightnees of a colour is represented by   ff
total absence of a colour is represented by     00
each character can have one of these values:   0, 1, 2, 3, 4, 5, 6, 7, 8, 9, a, b, c, d, e, f
it's a number system called hexadecimal, which gives you 256 shades of each colour
if it had been designed as two decimal characters it would have only given 0 to 99, which would have been less flexible.
here are some examples
