Confusion; Situational Awareness
Deviation - Track / Heading All Types; Deviation / Discrepancy - Procedural Clearance; Ground Incursion Taxiway
Air Traffic Control Issued New Clearance; Flight Crew Became Reoriented
Human Factors
Cleared runway 10L at B5 and went to ground control. Instructions were 'right on B; S; Q; P. As I turned on B it looked like the signage directed to turn left; but that put me on T not B. I had my [airport chart] out but misidentified where I was.  I should have had the First Officer help me find the way.
The pilot became disoriented during taxi and turned onto the incorrect taxiway due to signage and location confusion.
