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
RGB

Representing colors on the Web
– Hexidecimal system (RRGGBB)
– Named colors
– RGB values / percentages
Equivalent color units (CSS)
red
#f00
#ff0000
rgb(255,0,0)
rgb(100%, 0%, 0%)

CMYK
Technical mediating factors
or, 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

Human mediating factors

Visual perception
– Color sensitivity
– Visual color deficiency (“Color Blindness”)
– Eye fatigue
Emotions / mood
 Cultural background
 Aesthetics


Relativity!!

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
Rachael Gilg | INF 385E | October 12, 2004
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
Rachael Gilg | INF 385E | October 12, 2004
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
Rachael
Match
style to content
Gilg | INF 385E | October 12, 2004
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!
