Color Contrast Cards

Color Contrast Cards

Your baby can see color now – but the visual system is still building its strength.

These 30 cards follow the science of how color vision develops between 3 and 6 months: from bold primaries on high-contrast backgrounds to soft pastels and shade variations.

Four progressive series. Parent guide included.
Evidence-based, designed by NonstopMinds.

What's Inside

📖

Parent Guide

What your baby's color vision looks like right now, how to use the cards, and what each card trains.

🔴

Series 1: Hello, Color (Month 3)

Bold primaries on black and white backgrounds — the strongest color signal for a newly trichromatic brain.

🟣

Series 2: Color Meets Color (Month 3–4)

Green, purple, and the first color-on-color combinations. No more black-and-white safety net.

🟠

Series 3: A Colorful World (Month 4–5)

Warm tones, cool tones, multi-color patterns, and simple real-world shapes in color.

🩷

Series 4: Shades & Pastels (Month 5–6)

Light and dark versions of the same color. Pastels. The brain is learning that blue comes in many shades.

✅

Milestone Tracker

Track your baby's color vision development with a simple checklist based on CDC 2022 milestones.
