Black & White
Why Black & White? Black & white art is timeless, neutral, and adds style to any space, but it also stimulates, and encourages cognitive development in babies and young children. Intriguing imagery invites commentary and conversation, encouraging adults to engage more with baby, and each other.
Before a baby learns to reach and grab with their hands or crawl, a baby's brain undergoes an amazing period of development from birth to three — producing more than a million neural connections each second.
High-contrast imagery offers the best opportunity for newborns to focus on visual stimuli and promotes visual exploration and engagement. More than just entertainment, visual focus on a stimulus can foster a sense of calm and coherence in visually busy spaces.
0-3 Months
Early on, baby cannot see color well, but black and white patterns and distinct edges will engage young eyes and help them focus.
6-9 Months
Edges and patterns begin to take shape as a complete image.
9-12 Months
Depth perception is developing and dexterity begins to improve.
