As a developmental psychologist, I am horrified to see in the photo that there is a shades -
of - pink
Rock - a-Stack, not only because
of the absurdity
of gender -
typing toys by color alone, but also because it cripples the educational potential
of the
toy: the reduced contrast between the colors makes the rings harder to tell apart, and the use
of only three colors (bottom ring is purple, center pole is yellow) reduces opportunities for basic color learning.
