High Contrast Especially in black-and-white patterns, is considered important for stimulating and helping babies develop visually.
Here are some reasons why high contrast can be beneficial:

Visual Focus: Getting Babies Attention Newborn babies have limited eyesight and can see high-contrast patterns best. Black and white patterns are simple and easy to focus on.
Visual Development: Building Babies Eyesight A babies vision is still developing. By exposing them to contrasting patterns, it’s believed to help their visual skills come along. It helps build connections between their eyes and brains.
Keeping Attention: Keeping Babies Interested High contrast patterns grabs a babies attention. It can help them concentrate on what they’re looking at and possibly extend their attention span.
Sensory Stimulation: Tickling Babies Senses Visual stimulation is a part of the overall sensory stimulation that babies need for healthy development. High contrast contributes to this stimulation.
Easy Perception: Simple and Fun Babies tend to find it easier to notice simple visual patterns rather than complex ones. High contrast, like black and white patterns, offers this simplicity.

However, while high contrast is helpful, babies also benefit from a variety of visual stimulation as they get older. Gradually, they develop their ability to see colors and more intricate patterns.
