Using color()<\/code> you can give your pen a color. Using a list of predefined colors you can loop through the colors with a simple trick. %<\/code> operator will give the remainder from a division.<\/p>
colors[i%6]<\/code> will make sure colors only takes an index from 1 to 6 so each color gets assigned and then the index goes back to zero when i reaches a multiple of 6.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
