Short answer

Replace circular or neutral-colored informational badges with high-contrast, shield-shaped icons to communicate risk or high-content warnings.

Field: Innovation & Markets
Source: Nutrients (2023)
Method: Qualitative focus group discussions and inductive thematic analysis
Sample: 116 consumers
Evidence: Moderate effect

The combination of high-contrast black visuals and the cultural association of the shield shape with protection triggers a stronger psychological 'stop-and-read' response than traditional circular or colored signs. This innovation & markets research insight is drawn from a 2023 study published in Nutrients. Using Qualitative focus group discussions and inductive thematic analysis with 116 consumers, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Replace circular or neutral-colored informational badges with high-contrast, shield-shaped icons to communicate risk or high-content warnings.

Black shield-shaped warning labels increase perceived health risk and preference for nutritional information

Nutrients · 2023

Key Findings

Consumers showed a significant preference for black, shield-shaped labels containing bilingual (Chinese and English) text, finding them more authoritative and easier to interpret than other geometric variations.

Application

Design takeaway

Replace circular or neutral-colored informational badges with high-contrast, shield-shaped icons to communicate risk or high-content warnings.

How to apply

Implement a black shield-shaped 'High In [Nutrient]' badge on the top-right quadrant of product packaging to ensure visibility and trigger cognitive inhibition of unhealthy purchasing.

Method & Evidence

AimTo identify which specific visual design elements of front-of-package warning labels are most effective at influencing consumer perception and health-conscious decision-making in the Chinese market.

MethodQualitative focus group discussions and inductive thematic analysis

ProcedureParticipants evaluated several warning label prototypes varying in color and shape; they discussed their preferences for visual appearance, perceived utility, and information clarity while researchers coded responses into thematic categories.

Sample116 consumers

ContextRetail food and beverage packaging in China

Strengths & Limitations

Limitations

The study is qualitative and based on self-reported preference rather than observed purchasing behavior; results are specific to the Chinese cultural context and may vary in regions with different symbol associations.

Design Principles

"Hazard-Specific Iconography: Use shapes associated with protection and containment (shields) and high-contrast colors (black/white) to denote critical warnings over informational status updates."

Consumers often ignore standard nutritional grids due to information overload and low visual salience. Utilizing a distinct shape and color scheme that signifies a barrier or warning helps bypass cognitive fatigue, leading to faster identification of unhealthy nutrient levels (sugar, sodium, fat) at the point of sale.
