Is all this making sense to you? Once you see it, it seems so simple, doesn’t it? It won’t take long before you won’t even have to think about the ways to contrast type—you will just automatically reach for the right typeface. That is, if you have the right typeface in your computer. Fonts (typefaces) are so inexpensive right now, and you really only need a few families with which to make all sorts of dynamic combinations—choose one family from each category, making sure the sans serif family you choose contains a heavy black as well as a very light weight.
And then go to it. And have fun!
