Hey, did you know that LOGO has not only got one pencil inside his back plate? He's got a whole box of pencils in several colors. If you want to tell him that he should draw in another color, just use the command color followed by the color you want. For example...
...and so on. All colors you may use are listed in the help-file.
If you want LOGO to walk some steps without drawing, write up and he'll lift his pencil up. The command down lets him draw again.
