There are several practical reasons for this.
- Yellow Creates a Warm, Cheerful Impression
Yellow is a bright, attention-grabbing color. In food packaging, it can help a product feel energetic, friendly, and inviting.
The golden shade in the Lay’s logo also works naturally with the color of cooked potato chips. Although the logo itself doesn’t prove anything about how fresh or crispy the chips are, the color creates a visual association with golden, crunchy snacks.
- Simple Shapes Are Easy to Recognize
A logo needs to work in many different settings. It might appear on a large bag, a small promotional image, a vending machine, or a digital advertisement.
A bold circle and a contrasting banner remain recognizable even when the design is viewed quickly or reproduced at a smaller size.
A highly detailed illustration could be harder to recognize under those conditions.
- Consistent Branding Helps Connect Products
When related brands use similar colors or shapes, consumers may begin to recognize a connection between them, even without consciously analyzing the design.
The similarities between Lay’s and Frito-Lay offer an example of how a company can maintain some visual consistency while allowing individual brands to keep their own identities.
