1. A stylus, comprising:
an elongated housing having a tip end and a tail end along an axial direction;
an optical sensor configured to receive incoming light incident on the tip end;
a memory configured to store color information of the incoming light captured by the optical sensor;
a light emitter provided adjacent to the tip end and configured to emit color light corresponding to the color information stored in the memory;
a light blocker interposed between the optical sensor and the light emitter, the light blocker having a first surface facing the light emitter, and the first surface being mirror-finished to reflect the color light emitted from the light emitter;
a transmitter configured to transmit, from the tip end, a position signal; and
a control circuit configured to control the optical sensor, the light emitter, and the transmitter.
