Bert is a yellow person with on orange nose, a unibrow that moves when he gets mad, (but did not move in the 1969 - 1970 seasons), and a vertical striped shirt. He is serious in doing something right and smart, such as reading books, using important objects, and using his paper clips correctly.
Ernie is an orange person with a red nose and a red-and-blue striped sweater. His first Sesame Street series began with an even deeper voice, larger eyes, and yellow and purple stripes on his sweater. Ernie is very playful and friendly, and sometimes teases his best friend Bert, but he can do a lot of things, such as playing with his Rubber Duckie, and rock hunting (according to the 1969 season of Sesame Street).
