defining your palette
Newborns are nearly color-blind. For the first few months they can see only the brightest colors. Everything else is just shades of gray. By age three their vision is pretty normal, but by then they may have been spoiled on brightly-colored things because those things are often designed specifically for children. Almost as if young children inhabit a separate universe, color-coded so they know what's for them.
