Act I Sc ii Hamlet Context is important and it is pertinent to note here that Hamlet is speaking.
In this scene, Gertrude & Claudius have just admonished Hamlet for continuing to be somber about his father's death (which we learn was actually a murder.) Gertrude literally and figuratively tells him to "cast off his knighted colors."
(Stop wearing black and stop acting like a loyal knight of your father's.)
Hamlet's reply indicates that he is, essentially faking his depressed mood; it is a cover for his suspicions and his anger for his mother having married his uncle immediately upon the wake of his father's death:
HAMLET:
Seems, madam? Nay, it is. I know not seems.
'tis not alone my inky cloak, good mother,(80)
Nor customary suits of solemn black,
Nor windy suspiration of forced breath,
No, nor the fruitful river in the eye,
Nor the dejected havior of the visage,
Together with all forms, modes, shapes of grief,(85)
That can denote me truly. These indeed seem,
For they are actions that a man might play;
But I have that within which passeth show,
These but the trappings and the suits of woe.
