It's not clear what you are looking for, especially since the basic options are obvious:<ol> <li>Italics: No, we are looking for a <i>blue</i> car. <li>Bold: All purchases are final. <b>No warranty is implied</b>. <li>Caps: PUT THE GUN DOWN NOW! </ol> Of course you can use combinations of the above to suite the situation. With three orthogonal binary options, there are a total of 2<sup>3</sup> = 8 possibilities (including no emphasis at all). Any of them could be appropriate in a particular context or writing convention.
