High-contrast pictures make sense for newborns because the newborn visual system is much less sensitive to contrast and fine detail than an adult’s. The key idea is not that newborns “can only see black and white”—that is an oversimplification—but that strong luminance contrast is much easier for them to detect. Behavioral measurements in full-term newborns found very poor contrast sensitivity at birth, with contrast thresholds around 50%, followed by extremely rapid improvement over the first weeks of life.

What a good newborn high-contrast picture should look like

For roughly the first 0–2 months, I would design primarily for visibility rather than artistic complexity:

  • Very strong dark/light contrast. Black on white is the simplest and most reliable choice. White on black works too.
  • Large shapes and thick lines. Think broad stripes, circles, checkerboards, spirals, simple animals, leaves, hearts, or faces—not tiny patterns or detailed illustrations. Newborn contrast sensitivity is particularly limited for fine spatial detail.
  • One or a few elements per picture. A large black circle on white is more appropriate for a very young newborn than a complicated scene full of small objects.
  • Clear edges. Avoid gradients, watercolor effects and low-contrast textures during the earliest stage.
There isn't a medical specification saying a card must contain a particular percentage of black, a particular line thickness, or a particular number of shapes. The scientific evidence supports the principle of large, detectable, high-contrast patterns, rather than a standardized commercial-card format. Newborn pattern preferences can in fact be predicted substantially by what their immature contrast-sensitivity system can detect.

What about colors?

Black and white are excellent, but newborns do not literally live in a black-and-white world. Experiments have demonstrated some chromatic discrimination even in newborns. One laboratory study found that 74% of newborns discriminated a sufficiently strong red patch from achromatic backgrounds under its testing conditions; corresponding results were 14% for blue, 36% for green and 25% for yellow. Those percentages should not be interpreted as a universal ranking of babies' favorite colors—the experiment controlled luminance carefully and tested a specific visual ability.

Other studies show that newborn color discrimination requires colors to be much more saturated than adults require, and color discrimination develops considerably during the first few months. For example, newborns needed highly saturated red, green and yellow stimuli to distinguish them from white, while studies at 2–3 months show progressively better discrimination among colors.

So for designing cards, a sensible progression is:

Birth–~6 weeks: emphasize black + white. You can introduce a little highly saturated color, particularly red, but luminance contrast should remain the main feature.

~6–12 weeks: retain high contrast while adding strong saturated red, green, blue or yellow. For example, black + bright red or black + yellow is generally much more visually distinct than pale pink + cream.

After ~3 months: colors can become a much larger part of the pictures because both chromatic discrimination and general visual sensitivity are developing rapidly. Infant color vision continues maturing well beyond the newborn period.
