Color & Typography for the Web Rachael Gilg INF 385E: Information Architecture & Design October 12, 2004
Why are color & typography important in IA? • Structuring & ordering content • Create hierarchies / order • Aid navigation • Draw attention to page elements • Communicating using visual language • Solving problems
How Web color works • RGB vs. CMYK • Web vs. print • Additive vs. subtractive • Representing colors on the Web • Hexidecimal system (RRGGBB) • Named colors • RGB values / percentages RGB CMYK Equivalent color units (CSS) red #f00 #ff0000 rgb(255,0,0) rgb(100%, 0%, 0%)
Technical mediating factorsor, fear of the “dreaded 216” • Monitors (bit-depth setting) • 8 bit = 256 colors (4% of users) • 16 bit “high color” = 65,000 colors (30%) • 24 bit “true color” = 16.7+ million colors (66%) • Browsers • Dithering • “Web-safe” colors • Platforms / Monitors (color calibration) • Gamma (contrast) settings • 1.8 for Mac, 2.2 for PC statistics source:http://www.w3schools.com/browsers/browsers_stats.asp
Human mediating factors • Visual perception • Color sensitivity • Visual color deficiency (“Color Blindness”) • Eye fatigue • Emotions / mood • Cultural background • Aesthetics
Dimensions of Color • Hue = shade • Saturation = purity • Luminance = brightness • Relativity!!
Designing with color • Use contrast for structure & hierarchy • Color palettes • Monochromatic • Complementary • Analogous • Customization with CSS

II. Typography • “Typography exists to honor content.” - Robert Bringhurst • Verbal & visual • Creates hierarchy to understand relationships • Web typography considerations • Legibility • Readability • Accessibility / Customization
Evolution of digital typography • Graphical User Interfaces • HTML • Separates design from structure • Emphasis on interoperability, not visual style • CSS (Cascading Style Sheets) • separates visual style from document structure • greater typographic control with less code • more formatting options
Font styles on the Web • Best choice for screen: sans-serif, large size, exaggerated x-height Verdana x Times x • High contrast with background color • Anticipate size variability • Avoid ALL CAPS & use “downstyle” headlines • Use emphasis sparingly, 1 parameter • Colored / underlined have special meanings • Specify fonts for each platform • Be consistent • Match style to content
Formatting • Overall pattern of organization & visual contrast • Establish visual pattern using grid system • Alignment • Left-justified with ragged edge is best • Line Length • Columns of text no wider than 365 px. • Anticipate expanding layouts / wrapping • White space is your friend!
