why did they change oscar the grouch from orange to green
Oscar the Grouch The initial puppet, built by staff builder John Lovelady,[citation needed] was yellow, but since there was already a very large yellow character named Big Bird (also puppeteered by Spinney), they decided to change Oscar to orange. Oscar remained orange only for the first season of Sesame Street and then changed to green which became his permanent color. This was explained within the show by a visit to Swamp Mushy Muddy.[4]:59
