from the crayon website:
In response to educators' requests, “Prussian blue” is renamed “midnight blue.” Teachers felt that children were no longer familiar enough with Prussian history to recognize that this crayon color referred to the famous deep-blue uniforms of Prussian soldiers.
Well gee, they could have used it as an opportunity to, I don't know...educate? You just never hear much about the Prussian and the blue anymore.
