Helvetica light is the primary typeface. The preferred version is Helvetica Neue but other versions may be substituted if it is not available. This should be used for all body copy. To puchase Helvetica Neue go to www.fonts.com.
Hoefler Bold is the typeface to be used in headlines and only as all capitals. Hoefler text can be substituted in some situations. To purchase Hoefler Bold go to www.typography.com.
The SLCC brand uses two accent fonts, where appropriate. These should be used only as texture and highlights. The fonts are Helvetica Text and Hoefler Text Italic (never use the italic in all capitals).
Real handwriting is also appropriate as an accent. Never use digital handwriting typefaces as a substitute.
For web applications where Helvetica or Hoefler typeface cannot be used, substitute Georgia (headlines) and Arial (body copy).
