white, black and red are high contrast, supposed to be good for sight development. Or maybe brain development. Or maybe it was a fad 17 years ago. :)

Is there any study which tells how useful are high contrast things for kids?

When my son uses my mobile phone (which he knows how to turn on, off, unlock) - I generally turn brightness very low. This is in stark contrast to red/white :-)

He means those Alexander Calder spinning hanging sculpture things you hang over the crib.

so your 1.5 year old is already swiping ? maybe hold off on getting him an oculus rift, okay ? :)

My kid was an ipad expert by that age. 4-finger swiping and everything. At 2 he now knows his mom's unlock code and can punch it in. As long as a child has a healthy mix of real world and outdoors, I'm convinced that tablets and phones are amazing brain stimulation for children.

This high contrast stuff is for tiny infants.

Both are fine, I'm just too happy to see him picking words and associating context to them :)
