Here's an example of using different grain patterns to achieve contrast. In the picture below, I have used basswood for the really light colored feature strips, the rest is plain' ol' cedar. But note the two strips on either side of the "racing stripe", just outside the pinstripes; they're feature strips too, because of that wild plain-sawn grain pattern.
As an aside, I had planned to use a lot more of those plain-sawn strips on this deck, but there was so much "density contrast", as Gerald mentions, between the hard grain lines and softer wood between, that I was getting surface waves, so I aborted.
