Color
• We see the world via a reflective color model− Light strikes a surface and is reflected to our eyes--
Properties of surface dictate color− Printers
• Colors on display follow the emitted model• On monitors, typically RGB scheme
− 0-255 value each red, green, blue
− R: 170 G:43 B: 211
Fall 2002 CS/PSY 6750 13
Color Attributes
• Hue− native color, pigment
• Saturation− relative purity, brightness, or intensity of a
color• Value
− lightness or darkness of a color
Fall 2002 CS/PSY 6750 14
Color
• Use it for a purpose, not to just add some color in
Fall 2002 CS/PSY 6750 15
Color Guidelines
• Display color images on black background• Choose bright foreground color (white,
bold green,…)• Avoid brown and green as background
colors• Be sure fg colors contrast in both
brightness and hue with bg colors
Fall 2002 CS/PSY 6750 16
Color Guidelines
• Use color sparingly--Design in b/w then add color where appropriate
• Use color to draw attention, communicate organization, to indicate status, to establish relationships
• Avoid using color in non-task related ways

Color Guidelines
• Color is good for supporting search• Do not use color without some other
redundant cue− Color-blindness− Monochrome monitors− Redundant coding enhances performance
• Be consistent with color associations from jobs and cultures
Fall 2002 CS/PSY 6750 22
Color Guidelines
• Limit coding to 8 distinct colors (4 better)• Avoid using saturated blues for text or
small, thin lines• Use color on b/w or gray, or b/w on color• To express difference, use high contrast
colors (and vice versa)

aggression, love• Pink
