Brown eggs are a new invention.
You made paste eggs by hard boiling eggs in water that had onion skins in it. This turned the white egg a beautiful colour and then you could paint it or decorate it. You need to remember that you didn’t get brown eggs in those days, brown eggs are a new invention. Paste eggs were given as gifts on Easter Sunday before being either rolled or jarped on Easter Monday, unless you got a really special one that you wanted to keep.
