Make sure to leave enough space for the logo to “breathe.” The proper padding is at least the width of one full sized picturemark on the left and right (not counting the TM) and half a picture mark on the top and bottom.
Don't apply any effects to the logo
Don't change the colour of the logo
Don't flip the picturemark
Don't use the old logo
Don't put the coloured logo against a dark background
Don't put a border around the logo
