Utilizing chromatic contrast, specifically red text on a green background, negatively impacts reading performance for Arabic script, leading to a reduction in critical print size and reading acuity. This human factors research insight is drawn from a 2023 study published in Saudi Journal of Ophthalmology. Using Comparative experimental study with 15 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Prioritize achromatic contrast for Arabic text to ensure maximum readability and avoid performance degradation.

Key Findings
- 01Reading performance for critical print size (CPS) was significantly reduced with the red-green chart compared to the achromatic chart.
- 02Reading acuity (RA) was also significantly reduced with the red-green chart.
- 03Maximum reading speed (SLWPM) was similar between the two charts.
Application
Design takeaway
Prioritize achromatic contrast for Arabic text to ensure maximum readability and avoid performance degradation.
How to apply
When designing digital interfaces, educational materials, or any application featuring Arabic text, conduct A/B testing with different color palettes, paying close attention to chromatic combinations and their effect on reading metrics.
Project actions
- 01When investigating color and readability, consider the specific script being used (e.g., Latin, Arabic, Cyrillic) as visual properties differ.
- 02If exploring color, ensure controlled luminance levels to isolate the effect of chromatic contrast.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Developed a novel chromatic acuity chart for Arabic.
- +Quantified the impact of chromatic contrast on specific reading metrics.
Limitations
The sample size was small, and the study only tested one specific color combination. Results might differ with other colors or participant groups.
Reliability & validity
The use of standardized metrics like RA and CPS contributes to validity. Reliability could be enhanced with a larger sample size and repeated measures.
Think critically
How might the findings of this study apply to other non-Latin scripts, and what are the implications for globalized digital design?
Design Principles
"When designing for readability of specific scripts, especially those with unique visual characteristics like Arabic, rigorously test the impact of color and contrast combinations, favoring achromatic contrast for critical text elements."
This research highlights that color choices in design are not merely aesthetic but can have a direct impact on user performance and comprehension. Designers must consider the specific visual characteristics of the target script and the potential effects of chromatic contrast to ensure optimal readability and user experience.
What This Means for Your Design
Putting red words on a green background makes it harder to read Arabic, like losing two lines of text. It's better to use black text on white or white text on black for easier reading.

Paragraph starter
Research indicates that chromatic contrast can negatively impact reading performance for Arabic script. A study by Alsalem et al. (2023) found that using red text on a green background significantly reduced reading acuity and critical print size compared to achromatic contrast, suggesting that designers should prioritize achromatic color schemes for optimal Arabic text readability.
