YaleSites is a flexible website platform providing 3 themed designs with options for 7 different accent colors, 4 sidebar heading type styles, and effects for images. Site owners can selected from any of these options and can further customize their site as desired. The Yale typeface webfont is included for display headings.
I did the design work and theming in Drupal 7 using the Omega 3 base theme with a custom 978 grid. Each of the 3 designs has slightly different zone/region settings, and I devised the system of accent colors and other options.
