Bold Face & Colored Text

I read in a tread, someone construed using bold & colored text as being powerful. I always use bold & colored text in all my posts and personal emails because I feel it is easier to read and more creative than the washed out plain black text. I was wondering, is the use of bold and colored text considered offensive to this forums members? Should it only be used in anger or to make a point or is it OK whenever. Danny
