No surprise: the primary symptom of pink eye is an eye that has a pink appearance. Other symptoms of pink eye depend on the type of conjunctivitis you have:
Viral conjunctivitis. Watery, itchy eyes; sensitivity to light. One or both eyes can be affected. Highly contagious; can be spread by coughing and sneezing.
Bacterial conjunctivitis. A sticky, yellow or greenish-yellow eye discharge in the corner of the eye. In some cases, this discharge can be severe enough to cause the eyelids to be stuck together when you wake up. One or both eyes can be affected. Contagious (usually by direct contact with infected hands or items that have touched the eye).
Allergic conjunctivitis. Watery, burning, itchy eyes; often accompanied by stuffiness and a runny nose, and light sensitivity. Both eyes are affected. Not contagious.
