TECHNIQUES & TOOLS FOR USING COLOR IN COMPUTER INTERFACE DESIGN
Fundamentals of Color
To understand the potential of color in interfaces, we need to examine
some fundamental characteristics of color perception.
Motivation
Color has major impact on human-computer interaction.
Appropriate color use can aid user memory and facilitate the formation of
effective mental models.
However, ineffective use of color can
degrade an application's performance and lessen user satisfaction.
Mental Models & the Effective Use of Color
Simplicity
There is an inherent simplicity in color which should be used when developing the design.
. The four physiologically primary colors are red, green, yellow and
blue.
Consistency
Vital when assigning meanings to colours.
Can help establish intuitive consistency in the design.
The spectral and perceptual order red, green, yellow, blue
can guide the order of the concepts attached to colors.
Clarity
Clarity is also an important guideline for using color.
Color has been shown superior to black and white
for effective processing time of information and for memory performance.
Language of Color
The language of color is important in the use of color.
Due to this fact, existing symbolism and cultural use of
color should be considered when designing an interface.
Remember to document the colors that are used in the interface.
It is more difficult to use color effectively than it is to use it ineffectively.
Murch's Rules
• Avoid the simultaneous display of highly saturated.
• Pure BLUE should be avoided for text, thin lines, and small
shapes.
• Avoid adjacent colors that differ only in the amount of BLUE.
• Older operators need higher brightness levels to distinguish colors.
• Colors change in appearance as the ambient light level changes.
• The magnitude of a detectable change in color varies across the
spectrum.
• It is difficult to focus upon edges created by color alone.
• Avoid RED and GREEN in the periphery of large-scale displays.
• Opposit colors go well together.
• For color-deficient (color blind) observers, avoid single-color
distinctions.
