Short answer

Prioritize objective performance metrics over subjective aesthetic preferences when optimizing screen display parameters for efficiency, but acknowledge the role of colour in reducing discomfort.

Field: Human Factors
Source: Academic Publication (2020)
Method: Experimental research
Evidence: Moderate effect

While users may express a subjective preference for certain screen colours, these preferences do not consistently translate into measurable improvements in visual performance. This human factors research insight is drawn from a 2020 study published in Academic Publication. Using Experimental research, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Prioritize objective performance metrics over subjective aesthetic preferences when optimizing screen display parameters for efficiency, but acknowledge the role of colour in reducing discomfort.

Screen colour preferences don't always improve visual efficiency

While users may express a subjective preference for certain screen colours, these preferences do not consistently translate into measurable improvements in visual performance.

Academic Publication · 2020

Key Findings

01User efficiency was largely unaffected by changes in most screen parameters, suggesting default settings are near optimal.
02Subjective user preferences for background colours did not correlate with measurable improvements in efficiency, although some colours reduced visual discomfort.

Application

Design takeaway

Prioritize objective performance metrics over subjective aesthetic preferences when optimizing screen display parameters for efficiency, but acknowledge the role of colour in reducing discomfort.

How to apply

When designing interfaces, conduct user testing that includes both subjective feedback on comfort and objective measures of task completion time and accuracy.

Project actions

01When testing display settings, use a mix of questionnaires for preference and timed tasks for performance.
02Consider how different visual impairments might interact with your chosen display settings.

Method & Evidence

AimTo investigate the impact of screen display parameters, including colour, on the visual comfort and efficiency of computer users.

MethodExperimental research

ProcedureA series of experiments were conducted using tasks such as search tests and reading speed assessments (modified MNRead and Wilkins Rate of Reading tests) to evaluate user efficiency. Participants were exposed to varying contrast levels, font sizes, font styles, letter spacing, contrast polarity, antialiasing, and screen colours.

ContextComputer display design and user interaction

Variables

IVScreen display parameters (contrast, font size, font style, letter spacing, contrast polarity, antialiasing, screen colour)

DVUser efficiency (performance in search tasks, reading speed), subjective comfort

CVUser vision (normal vision), workstation design, working practices, refractive errors, binocular vision anomalies (controlled for or noted as potential confounds)

Strengths & Limitations

Strengths

+Systematic examination of multiple display parameters.
+Use of objective performance measures alongside subjective feedback.

Limitations

The specific tasks used might not represent all real-world computer use scenarios.

Reliability & validity

Reliability could be assessed by repeating tests on the same participants. Validity would depend on how well the chosen tasks represent real-world computer use and visual demands.

Think critically

To what extent should subjective user preferences for visual elements like colour be prioritized over objective performance metrics in interface design?

Design Principles

"User interface design should be validated through objective performance measures, not solely subjective preference."

This insight challenges the assumption that catering to subjective user preferences for screen aesthetics will automatically lead to better usability. Designers must balance user preferences with objective performance metrics to ensure truly effective design outcomes.

What This Means for Your Design

Just because someone likes a certain colour on a screen doesn't mean it actually helps them see or work better.

Paragraph starter

Research indicates that while users may express preferences for certain screen colours, these preferences do not consistently translate into improved visual efficiency. For instance, a study by D'Ath (2020) found that subjective preferences for background colours did not lead to measurable gains in task performance, even though some colours reduced subjective discomfort. This highlights the importance of validating design choices with objective performance metrics rather than relying solely on user preference.
