In the typeface family "Complements" two sets of characters complement each other, so much so that they work together much better than they work separately. The two sets are designed to alternate and this alternating is done automatically in applications that support the OpenType feature Contextual Alternatives. Complements is purely for show and display; it is a horrible choice for text. The spacing is very tight, which works well for very large point sizes. At smaller point sizes the user may want to increase character spacing. The typeface is monospaced. If the spacing between words is too large, substitute the non-breaking space (or the underscore) for the space character. Complements is geometric, bizarre, and hard to read, all characteristics that catch the reader's attention.
Complements comes in two styles, regular and outline. The outline style was designed to be used in a layer over the regular style. It is available from myfonts and fontspring.
